DESCRIPTION:Title: <a href="https://researchseminars.org/talk/VSGS/119/">N
 odal counts for the Robin problem on Lipschitz domains.</a>\nby Katie Gitt
 ins (Durham University) as part of Virtual seminar on geometry with symmet
 ries\n\n\nAbstract\nWe consider the Courant-sharp eigenvalues of the Lapla
 cian (with boundary conditions) on Euclidean domains. That is\, the eigenv
 alues that have a corresponding eigenfunction which achieves the maximum n
 umber of nodal domains given by Courant's theorem. We will first give an o
 verview of previous results for the Courant-sharp Dirichlet\, Neumann\, an
 d Robin eigenvalues of the Laplacian. In particular\, Pleijel's theorem an
 d upper bounds for the number of Courant-sharp eigenvalues. We will then p
 resent recent joint work with Asma Hassannezhad\, Corentin Léna\, and Dav
 id Sher which extends previous results in various directions.\n
