Hi all,
I am struggling to find any elementary material on the "gradient flow of a functional" concept.
From introductions in advanced papers I seem to have understood that, assigned a functional F (u), the gradient flow is charactwerized by an equation of the type Du / Dt = P u , where P is a differential operator related to the functional's Euler- Lagrange equation.
I would like to understand more, but was surpsrisngly unable to find any sources on the Internet.
Can anybody suggest a good starting reading?
Many thanks for any help
