Title: Non-scattering wavenumbers

Abstract: I will discuss some recent results about non-scattering wave-numbers in the context of the Helmholtz equation and penetrable scatterers. In particular, I will discuss the dependence of the number of such wave-numbers on the geometry of the scatterer. As a starting point I will introduce the notion of (interior) transmission eigenvalues and relate the non-scattering wave-numbers to these. This is joint work with Jingni Xiao.
