We consider methods based on the topological degree theory to compute periodic orbits of area preserving maps. Numerical approximations of the Kronecker integral and the application of Stenger's method allows us to compute the value of the topologica

We consider methods based on the topological degree theory to compute periodic orbits of area preserving maps. Numerical approximations to the Kronecker integral give the number of fixed points of the map provided that the integration step is "small

We study in great detail the geometry of the homoclinic tangle, with respect to the energy, corresponding to an unstable periodic orbit of type 1:2, on a surface of section representing a 2-D Hamiltonian system. The tangle consists of two resonance a

The trapping of 2D localised solutions that may exist for a generalised (2 + 1)-dimensional nonlinear Schrödinger equation with a random external potential is analysed. The method used is based on the stability properties of a system of stochastic O

We study the existence, formation, and stability of quasi-one-dimensional (stripes) and two-dimensional (bullets) spatio-temporal soliton solutions for a (2 + 1)-dimensional modified nonlinear Schrodinger equation, in the presence of the self-steepen

The conditions for trapping of Schrodinger solitons in a random potential are analysed. A stochastic ODE is derived for the position of the soliton centre and the behaviour of its solution is studied for different types of stochasticity. The problem

The bifurcations of a class of mappings including the beam-beam map are examined. These maps are asymptotically linear at infinity where they exhibit invariant curves and elliptic periodic points. The dynamical behaviour is radically different with r
