SUMMARY:Combinatorial methods in the study of moduli spaces
DESCRIPTION:Speaker: Melody Chan\, Brown University\n\nI will discuss some combinatorial methods used to study the geometry of moduli spaces: spaces which parametrize geometric objects. These spaces play a central role in the field of algebraic geometry, the study of spaces that are patched together from zero sets of systems of polynomial equations. …

SUMMARY:Exploiting Structure in (Derivative-Free) Composite Nonsmooth Optimization
DESCRIPTION:Speaker: Matt Menickelly\, Argonne National Laboratory\n\nWe present new methods for solving a broad class of bound-constrained nonsmooth composite minimization problems. These methods are specially designed for objectives that are some algebraically specified (nonsmooth) mapping of a vector of outputs from a computationally expensive (black-box) function. …

SUMMARY:Expansivity for the action of general groups
DESCRIPTION:Speaker: Alejandro Maas\, University of Chile\n\nS. Schwartzman in his Ph.D. thesis in the 1950s observed a deep result in dynamical systems. It states that a homeomorphism of a compact metric space always has two points whose iteration into the future remain closer than an arbitrary small distance. The same occurs when we consider the past. A …

SUMMARY:Kinetic models of particle systems
DESCRIPTION:Speaker: Cory Hauck\, Oak Ridge National Laboratory\n\nKinetic models are used to simulate the collective behavior of particle systems. They provide a mesoscopic description that forms a link between continuum fluid models, which are not valid in non-equilibrium settings, and molecular dynamics models, which are often too expensive for practical …
