Minimizing movements for dissipative systems that are not gradient flows

Mimura Yoshifumi

Bulletin of the Polish Academy of Sciences. Mathematics

2022

Vol. 70, no. 2

133--149

The time discretization method, which is a method of constructing time global solutions for gradient flows, is applied to dissipative systems in Hilbert spaces, which are not necessarily gradient flows. Equations with perturbation terms added to gradient flows are considered, and when the perturbation term is smaller than the principal term in an analytical sense, the dissipative structure of the energy is maintained, and the existence of time global solutions is shown by the time discretization method.

Convergence Analysis for Principal Component Flows

Yoshizawa S., Helmke U., Starkov K.

International Journal of Applied Mathematics and Computer Science

2001

Vol. 11, no 1

223-236

A common framework for analyzing the global convergence of several flows for principal component analysis is developed. It is shown that flows proposed by Brockett, Oja, Xu and others are all gradient flows and the global convergence of these flows to single equilibrium points is established. The signature of the Hessian at each critical point is determined.
