Computing Cloud Dynamics with an Adaptive Monte Carlo Sampling Method Thomas Roessler University of Wisconsin-Milwuakee Graduate Student "Atmospheric models usually have simple parametrizations of subgrid variability that do not include all processes. The model Cloud Layers Unified By Binormals (CLUBB)... Read More

Around a Big Mapping Class Group Juliette Bavard University of Chicago PostDoc "The  mapping class group of the plane minus a Cantor set arises naturally in many dynamical contexts. To study this "big mapping class group", we can consider its... Read More

Using Magnus Representations to Study Automorphism Groups of Free Groups for Both the Study of Mapping Class Groups and Galois Theory, it is Useful to have Tools to Study Automorphism Groups of Free Groups. We Will Discuss One Particular Such... Read More

The q-Difference Noether Problem for Complex Reflection Groups and Quantum OGZ Algebras Jonas Hartwig Assistant Professor of Mathematics Iowa State University "For any complex reflection group G=G(m,p,n), we prove that the G-invariants of the division ring of fractions of the... Read More

Topological Complexity Alexander Dranishnikov University of Florida Distinguised Professor of Mathematics “Topology of the configuration space of a robot or any mechanical system is usually quite complicated. This implies that a   continuous motion planning algorithm of such system is impossible.... Read More
