DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MPHA/4/">Emb
 edded eigenvalues of the Neumann Poincaré operator</a>\nby Wei Li (LSU) a
 s part of TAMU: Mathematical Physics and Harmonic Analysis Seminar\n\n\nAb
 stract\nThe Neumann-Poincaré (NP) operator arises in boundary value probl
 ems\, and plays an important role in material design\, signal amplificatio
 n\, particle detection\, etc. The spectrum of the NP operator on domains w
 ith corners was studied by Carleman before tools for rigorous discussion w
 ere created\, and received a lot of attention in the past ten years. In th
 is talk\, I will present our discovery and verification of eigenvalues emb
 edded in the continuous spectrum of this operator. The main ideas are deco
 upling of spaces by symmetry and construction of approximate eigenvalues. 
 This is based on two works with Stephen Shipman and Karl-Mikael Perfekt.\n
