Mathematical theories underpinning different classes of phenomena possess a universal character, with the same mathematical equations appearing to govern phenomena of different nature. The Mathematics of Complex and Nonlinear Phenomena can therefore be seen as the seed for crossfertilisation between different research areas and disciplines.
Complexity and nonlinearity are often concomitant features of realworld phenomena that are commonly associated to the notion of disorder and chaos.
Unexpectedly, disordered structures and chaotic behaviours observed from fluid dynamics, classical and quantum physics to biological systems, economic and social sciences can be related, under suitable conditions, to the emergence of beautiful ordered and stable structures, as well as coherent, cooperative or cyclic behaviours.
The formation of tsunamis and rogue waves, laser pulses, turbulence of accretion disks around black holes, phase transitions from ordered to disordered states of matter are just some examples where disorder/chaos and order/coherence arise as two sides of the same coin.
Most amazingly, mathematical theories underpinning such different classes of phenomena turn out to possess a universal character so that the same mathematical equations appear to govern phenomena of (seemingly) different nature. Hence, the Mathematics of Complex and Nonlinear Phenomena (MCNP) can be seen naturally as the seed for crossfertilisation between different research areas and disciplines.
Northumbria's MCNP Research Group conducts interdisciplinary research aiming at impacting on challenges posed by a fastchanging world. It is engaged in groundbreaking research in the hottest areas of modern Mathematics, Physics, Biology and other sciences, including multiple international collaborations with other leading experts.
MCNP research activity focuses mainly on the advancement of mathematical methods for the extensive study of nonlinear partial differential equations and dynamical systems. This ranges from their classification to the development of analytical and numerical techniques to calculate or extract qualitative and quantitative information on their solutions, e.g. asymptotic methods, multiscale analysis, nonlinear stability analysis, bifurcation theory and methods of integrable systems.
The findings of the MCNP research group are concerned with the study of mechanisms for the formation and propagation of nonlinear classical and quantum waves, coherent and localised structures, dynamic emergence of instabilities and singularities under different regimes of dispersion and dissipation, diffraction, interference, delays, phase transitions, classical and quantum chaos, geometric structures associated to differential equations and Riemann surfaces.
Applications that are currently under investigation include the solutions of models for ferromagnetic nanostructures, topological insulators, climate components, magnetohydrodynamics, biological phenomena as cyclic rhythms in glucose regulation, liquid crystals and complex networks.
The MCNP research group has successfully received funding from EPSRC, Leverhulme Trust, London Mathematical Society.

Title: Rapid dynamics in solidstate magnetism
Abstract: Magnetism in solids is a fascinating yet complex phenomenon that encompasses vastly different length and time scales. This complexity is typically resolved by establishing equations that are valid at different scales. For example, magnetic dynamics at the atomic level can be described by a discrete system of Schrödinger equations while microscopic magnetisation dynamics is described by a vectorial partial differential equation known as the LandauLifshitz equation. However, such a distinction of scales is challenged when considering the problem of a magnetic material that dynamically evolves towards equilibrium from a randomised state. In this talk, I will give an overview of solidstate magnetism at these extreme conditions, the experimental capabilities available, and the current theoretical understanding of the underlying physical phenomena. I will also discuss the advantages of a dispersive hydrodynamic interpretation of magnetisation dynamics in the context of rapid magnetic soliton nucleation and evolution. Finally, I will outline future research directions and outstanding challenges of the research field towards technological applications.

Title: Soliton and breather gases for the focusing nonlinear Schrödinger equation
Abstract: Solitons and breathers are localized solutions of integrable systems that can be viewed as "particles" of complex statistical objects called soliton and breather gases. In this talk, we discuss spectral theory of a generalized breather gas by considering a special, thermodynamic type limit of multiphase (finitegap) solutions of the focusing nonlinear Schrödinger (fNLS) equation. The family of generalized breather gases includes gas of fundamental solitons and gas of conventional breathers (solitons on finite background) as particular cases. We consider several particular cases of the generalized breather gas including the socalled bound state soliton gas, as well as some transitional regimes (condensate and ideal gas limits

Title: Reflectionless solutions for square matrix nonlinear Schroedinger equation with vanishing boundary conditions
Abstract: After a quick review of the direct and inverse scattering theory of the focusing ZakharovShabat system with symmetric nonvanishing boundary conditions, we derive the reflectionless solutions of the 2 × 2 matrix NLS equation with vanishing boundary conditions and four different symmetries by using the Marchenko theory. Since the Marchenko integral kernel has separated variables, the matrix triplet method  consisting of representing the Marchenko integral kernel in a suitable form  allows us to find the exact expressions of the reflectionless solutions in terms of a triplet of matrices. Moreover, since these exact expressions contain matrix exponentials and matrix inverses, computer algebra can be used to "unpack" and graph them. Finally, it is remarkable that these solutions are also verified by direct substitution in the 2 × 2 NLS equation.
This is a joint work with Francesco Demontis (University of Cagliari, Italy) and Alyssa Ortiz (University of Colorado at Colorado Springs, USA).

Title: On destruction of adiabatic invariance
Abstract: In many problems of classical mechanics and theoretical physics dynamics can be described as a slow evolution of periodic or quasiperiodic processes. Adiabatic invariants are approximate first integrals for such a dynamics. Existence of adiabatic invariants makes dynamics close to regular. Destruction of adiabatic invariance leads to chaotic dynamics. In the talk it is planned to present a review of some mechanisms of destruction of adiabatic invariance with examples from charged particle dynamics.

Title: Stability optimization for polynomials and matrices
Abstract: Suppose that the coeffcients of a monic polynomial or entries of a square matrix depend affinely on parameters, and consider the problem of minimizing the root radius (maximum of the moduli of the roots) or root abscissa (maximum of their real parts) in the polynomial case and the spectral radius or spectral abscissa in the matrix case. These functions are not convex and they are typically not locally Lipschitz near minimizers. We first address polynomials, for which some remarkable analytical results are available in one special case, and then consider the more general case of matrices, focusing on the static output feedback problem arising in control of linear dynamical systems. We also briefly discuss some spectral radius optimization problems arising in the analysis of the transient behavior of a Markov chain and the design of smooth surfaces using subdivision algorithms. Finally, time permitting, we discuss optimization of pseudospectra of matrices.

Title: A spectral method for ''bipartizing'' a network and detecting a large anticommunity
Abstract: Relations between discrete quantities such as people, genes, or streets can be described by networks, which consist of nodes that are connected by edges. Network analysis aims to identify important nodes in a network and to uncover the structural properties of a network. A network is said to be bipartite if its nodes can be subdivided into two nonempty sets such that there are no edges between nodes in the same set. It is a difficult task to determine the closest bipartite network to a given network. In this talk, I will describe how a given network can be approximated by a bipartite one by solving a sequence of fairly simple optimization problems. The proposed algorithm also produces a node permutation which makes the possible bipartite nature of the initial adjacency matrix evident and identifies the two sets of nodes. It will be also showed how the same procedure can be used to detect the presence of a large anticommunity in a network and to identify it.

Title: Topological defects, deformed lattices and spontaneous symmetry breaking
Abstract: External conditions have a dramatic impact on the way symmetry breaking occurs. I will review some recent (and some less recent) results of symmetry breaking in curved spacetime. Flirting with the contemporary interest toward 2D engineered material, I will then move on potential applications on geometrically deformed lattices. In a curved background, the natural expectation is that curvature works towards the restoration of internal symmetries. I will show instead that, for topological defects, the competing action of the locally induced curvature and boundary conditions generated by the nontrivial topology allows configurations where symmetries can be spontaneously broken close to the core.

Title: From condensed matter physics to probability theory
Abstract: The primary goal of condensed matter physics is to understand the behaviour of electrons in solids. The basic laws are well understood, but the large number of interacting particles makes it challenging. A popular approach is to introduce simple models and to use the setting of statistical mechanics. I will review quantum spin systems and their stochastic representations in terms of random permutations and random loops. I will also describe the *universal* behaviour that is common to loop models in dimensions 3 and more.

Title: Miura transformations from Novikov algebras
Abstract: For the KdV equation, the Miura map transforms the second Hamiltonian structure into the first Hamiltonian structure. Multicomponent generalization of KdV's biHamiltonian structure have been known for decades  they date back to the work of Gelfand and Dorfman, and Balinskii and Novikov  and are defined in terms of algebraic structures known as Novikov algebras. The corresponding Muira map for these structures was constructed by Balinskii and Novikov only in the case where the algebra is commutative. In this talk a construction will be presented which solves the problem of the constructive of these maps in general.

Title: Quantummechanical backflow and scattering theory
Abstract: Backflow is the phenomenon that the probability current of a quantum particle on the line can flow in the direction opposite to its momentum. This talk will revisit this effect in the context of potential scattering in quantum mechanics. It turns out backflow is universal in the sense that it occurs in every potential (in a large class), and has always bounded spatial extent. On a mathematical level, these results are proven by establishing (lower) bounds on the spectra of certain integral operators. These general investigations are complemented with concrete examples and numerics.

Title: KAM theory for pure gravity water waves in finite depth
Abstract: In this talk I will present some recent results concerning the existence and the stability of quasiperiodic solutions for the WAVES EQUATIONS ( 2DEuler equation of an irrotational and incompressible fluid in an ocean with finite depth under the action of the gravity). After an overview of the classical methods used in the KAM theory for semilinear partial differential equations, I will focus on the method used to deal with fully nonlinear PDEs and in particular I will describe the KAM results obtained for the water waves equation. The main difficulties are:
1) the fully nonlinear nature of the gravity water waves equations (the highest order xderivative appears in the nonlinear term but not in the linearization at the origin)
2) the linear frequencies grow only in a sublinear way at infinity.
In order to overcome the small divisors problem, the proof is obtained by a Nash Moser iteration. The key point is to solve the linearized PDE at any approximate solution. This requires to combine perturbation theory and Pseudo differential calculus.

Title: Patterning, segregation and differentiation in human embryonic stem cell colonies
Abstract: The maintenance of the pluripotent state in human embryonic stem cells (hESCs) is highly crucial for their application in the laboratory as a tool for drug testing and the study of cell based therapies. Currently the selection of the best quality cells and colonies for propagation is done empirically in terms of their displayed features, such as a round nucleus, scant cytoplasm, prominent/abundant nucleoli and less intercellular spacing between the individuals in the bulk. Using image analysis and computational tools, we quantify these properties using phase contrast images of hESCs colonies of different sizes (0.1  1.1 mm2) during day 2, 3 and 4 of plating.
We identify their main characteristics such as the number of nearest neighbours, mean cell area, among other features. We discuss the mechanisms underlying the formation of these structures in vitro and explore, through a dynamical model in which the cells are represented as Voronoi tessellations of the space, how the cells might attain different levels of pluripotency and differentiate towards the three germs layers.

Title: The relationship between bed and surface topography on glaciers and ice sheets
Abstract: Glacier flow is an example of a gravity driven nonlinear viscous flow at low Reynolds numbers. As a glacier flows over an undulating bed, the surface topography is modified in response. Some information about bed conditions is therefore contained in the shape of the surface and the surface velocity field. I will present theoretical and numerical work on how basal conditions on glaciers affect ice flow, and how one can obtain information about basal conditions through surfacetobed inversion. I'll give an overview over inverse methodology currently used in glaciology, and how satellite data is now routinely used to invert for bed properties of the Greenland and the Antarctic Ice Sheets.
