The spectral instability of non-normal operators is a phenomenon which has recently attracted increasing interest in applications. It gives an obstruction to the accurate computation of eigenvalues of large non-normal matrices and has applications in a wide field, from random matrix theory, the stability of flows to things as mundane as brake squeal. In this talk, we shall review the spectral instability of semiclassical differential operators.

Coffee and tea is served at 3:30 in the lunch room.
