Abstract

 |
 |
We consider evolution equations induced by an important class of quadratic differential operators which arise from the Weyl quantization of quadratic forms. This class of operators has a number of special features which makes their study quite involved. In general:
1) They are far from being selfadjoint,
2) Their eigenvectors form a minimal set with dense span, but not a Riesz basis,
3) The norm of their resolvent grows exponentially towards infinity within certain regions in the complex plane.
The aim of the talk is to present a model for such operators on Fock spaces in several complex variables, which offers a complex analysis perspective and can be used to address a number of questions about the solutions of these evolution equations.
The material is based on joint work with J. Viola. |
