"Spectral Singularities of Non-seilfadjoint Operators"
By
Abstract: In this talk, we describe a concept of
spectral singularity which, though impossible for selfadjoint operators, is rather
typical for non-selfadjoint operators. We identify spectral singularities of
some differential operators with complex-valued coefficients.
Tea and cookies will be served before the
