题目：On the Cauchy problem for a degenerate hyperbolic equation
报告者：Ingo Witt 教授
摘要：In this talk, I will give a short introduction to Floquet-Bloch theory and discuss among others spectral properties and the limiting absorption principle for Schrödinger operators with periodic potentials. Eventually, I will provide an intrinsic characterization of the radiation conditions that arise in that case. This is joint work with Nguyen Thai Ngoc (Hanoi).
