Chaos is cosmological models with scalar fields
(introduction to my thesis) 
I will give an introduction to the models we are working on,
providing a description of the dynamics that will lead to a
discrete map. This map is the main focus in my thesis, so I will
present some early results of our investigation of it.

Construstion of an Anosov diffeomorphism on an infranilmanifold 
Infranilmanifolds are obtained from the group action of an
almostBieberbach group on a connected simplyconnected nilpotent
Lie group. After a brief introduction, a tiny mistake in M.Shub's
example will be indicated and corrected. Next, the generalization
to higher dimensions of the example inspired by M. Shub follows
and the talk will be finished by an outlook.

Oriented Shadowing in Bianchi Class A Cosmologies ("Moscow Rehearsal") 
Bianchi Class A cosmological models have been studied extensively
as a model for chaotic (oscillatory) curvature blowup in
solutions to the Einstein field equations. This chaos is due to
the presence of the so called Mixmaster attractor in the
corresponding ODE system. This attractor consists only of
heteroclinic trajectories, and exhibits nonuniformly hyperbolic
dynamics. Physical heuristics suggest that the behaviour of the
system close to the attractor is determined by the behaviour on
the attractor (BKL Conjecture). However, rigorous results in this
direction are rather sparse.
In this talk, we will present a new result in this context, namely
that trajectories converging to the attractor are approximated by
heteroclinic chains. This theorem and its proof are related to the
geometric notion of oriented shadowing.

The Neumann problem in oscillating thin domains 
In this talk we discuss some recent results about the asymptotic
behavior of the solutions of a parabolic problem with homogeneous
Neumann boundary conditions posed on thin domains with locally
periodic structure on the boundary. We discuss the limit problem
dependence with respect to the geometry of the thin domain also
studying the convergence of the global attractors.

Beyond the blowup 
In this seminar talk I attempt to prove a global continuation
result for the nonlinear heat equation in the complex time
direction in a special case. This allows to draw some conclusions
on the behaviour of the solution near blowup for example on the
blowup rate and the local profile around the blow up point of the
continued solution. If there is still some time left, I will also
discuss possible further research directions.
