Calculus in banach spaces

WebThe following result is a basic result for the direct method of the calculus of varia-tions. Theorem 2 If X is a re exive Banach space and I: X!IR is swlsc and coercive then there exists u 2Xsuch that I( u) = inf u2XI(u). Proof. Let u nbe a sequence such that I(u n) !inf XI. Such a sequence will be always called minimizing sequence.
