Rigorous Foundation of the Brockett-Wegner Flow — •Volker Bach¹ and Jean-Bernard Bru² — ¹Institut für Mathematik FB 08; Universität Mainz; 55099 Mainz — ²Department of Mathematics, University of the Basque Country UPV/EHU, Leioa, Spain

The Brockett-Wegner flow was found independently by Brockett and Wegner in the early 1990ies to diagonalize self-adjoint matrices by a time-dependent Schrödinger equation. The lecture will discuss the mathematical foundation of this flow and its application to the diagonalization of quadratic operators in quantum field theory (a warm-up application which represents an alternative to a Bogolubov transformation).
