SUMMARY:Generalized Eigenfunction\, Singularity Expansion and Time-Depende
 nt Wave Scattering - Mike Meylan (University of Newcastle\, Australia)
DTSTART:20230126T160000Z
DTEND:20230126T170000Z
UID:TALK195961@talks.cam.ac.uk
DESCRIPTION:I will talk about methods to solve the time-dependent wave sca
 ttering problem from the frequency domain solutions via the generalized ei
 genfunction method. This method is based on a diagonalization of the under
 lying self-adjoint problem\, which has a continuous spectrum\, using the s
 ingle frequency solution. I will also show how we can find approximate sol
 utions using a projection onto the poles of the analytic extension of the 
 solution. The talk will touch on several open questions (or more accuratel
 y\, questions to which I do not know the answer).
