## Dynamical and computational aspects of double-bracket flows## Arieh Iserles## Department of Applied Mathematics and Theoretical Physics, University of Cambridge, UK
In this talk we discuss recent work (joint with Tony Bloch) on the
double-bracket equation (in short, DB) We demonstrate that fixed points of the flow possess an intriguing optimal property with respect to a range of different norms. Turning our attention to a generalization of the DB equation, we prove that it might possess a more complicated structure of its equilibria, which can be related to the geometry of the Horn-Schur polytope. |
