I will discuss the following question: Is any smooth or analytic orientation preserving diffeomorphism of the circle $f$ with an irrational rotation number $\alpha$ almost reducible in the sense that there exists a sequence of smooth or analytic...

Dr Frohlich is Associate Director of the Institute for Geophysics and Senior Research Scientist in the Jackson School of Geosciences. Following his talk there will be an open panel discussion. Confirmed panelists will include Mirko van der Baan and...

In this talk, I will present the chaotic phenomenon of a dynamical system with positive entropy. It is shown that a dynamical system has positive entropy if and only if it has a weak horseshoe. Particularly, I will show that a Lorentz attractor has a...

The first part of the summer school takes place parallel to the CAIMS Annual Meeting. The summer school is followed by the Sixth International IMS-FIPS Workshop, which takes place July 7-9, also at the University of Alberta in Edmonton.

The purpose of this summer school is to focus on the interplay of dynamical and biological systems, developing the rich connectionbetween science and mathematics that has been so successful to date. Our focus will be on understanding the mathematical...

Entropy is one of the most important invariants in dynamical systems, in both measure-theoretic and topological settings. The original Kolmogorov-Sinai entropy was introduced for integer group actions in the late 1950s and extended to amenable group...

We present a technique called M-adaptation, based on the mimetic finite difference method, for minimizing numerical dispersion error in edge discretizations of the time-domain vector wave equation on square meshes. The temporal discretization uses...

We derive boundary conditions for the vorticity equation with solid wall boundaries. The formulation uses a Dirichlet condition for the normal component of vorticity, and Neumann type conditions for the tangential components. In a Galerkin (integral)...

The lecture deals with the homogenization of strongly heterogeneous elastic plates satisfying the Reissner-Mindlin or the Kirchhoff-Love hypotheses. We rigorously justify the limit models obtained by the asymptotic analysis which describe the...
