Events for September 26, 2017 from General and Seminar calendars

Working Seminar in Orbit Equivalence and Measured Group Theory

Time: 10:00AM - 11:00AM

Location: BLOC 624

Speaker: Robin Tucker-Drob

Title: "Asymptotically invariant sequences and approximate finiteness" after Jones and Schmidt

Abstract: This talk will be an introduction to strongly ergodic actions. I will also discuss the notion of stable actions, introduced by Jones and Schmidt.

Speaker: Giles Auchmuty, University of Houston

Title: Nonlinear PDEs Seminar

Abstract:
Title: Energy Bounds for Planar Div-curl Boundary Value Problems

Abstract: This talk will describe the derivation of sharp L^2 norm estimates for the solutions of div-curl boundary value problems on bounded Lipschitz planar regions Nontrivial prescribed tangential, normal or mixed boundary condition problems are considered of the type that arise in stationary electromagnetic eld modeling. The solutions are found using special decompositions of the vector elds in terms of scalar potentials, stream functions and harmonic elds. Explicit spectral formulae for the solutions are derived that involve various eigenvalues and eigenfunctions of the Laplacian including the Steklov eigenvalues and eigenfunctions. The bounds depend on certain least eigenvalues and the given data.
