Abstract: Mautner phenomenon gives invariance of unitary representation of simple Lie group. The talk will focus on the case of SL(2,R) and introduction to G-space.

Abstract: Classical numerical integrators do not preserve symplecticity, a structure inherent in Hamiltonian systems. Thus, the trajectories they produce cannot be expected to possess the same qualitative behavior observed in the original system. Pooling recent results from O'Neale and West, we explore a particular class of numerical integrators, the variational integrator, that preserves one aspect of the range of behavior present in Hamiltonian systems, the periodicity of trajectories.

Abstract: Chaotic systems are characterized by sensitive dependence on initial conditions, dense trajectories and dense periodic points. Due to their occurrence in a wide variety of dynamical systems, they can usually be rigorously studied only if accompanied by some assumptions on the geometric / differential properties of the transformation. One geometric structure which is well understood is the class of Anosov diffeomorphisms or more generally, completely hyperbolic systems and to some extent, partially hyperbolic systems. A weaker version of these rather stringent assumptions is the concept of invariant cones. This is an invariant structure in the tangent bundle of a map and we will explore various consequences of this invariant structure. We will mostly focus on a broad class of maps on the torus and derive various properties and also discuss the interplay between them, under the assumption that a "dominated invariant cone system" is present.
