Invariant Sets of Descending Flow in Critical Point Theory with Applications to Nonlinear Differential Equations [PDF]

open access: yesJournal of Differential Equations, 2001
Properties of invariant sets of descending flow defined by a pseudogradient vector field of a functional in a Banach space are studied. In this way, several critical points can be found by constructing different invariant sets on which the functional is ...
