Introduction to minimax methods
nell'ambito della serie: TOPICS IN MATHEMATICS 2018/2019
We will introduce the basic tools for the topological methods in critical points theory: the Palais-Smale compactness condition and the deformation lemma. Starting from the finite dimensional case, we will illustrate how the minimax argument works. Eventually, we will show some applications to problems in infinite dimensional setting.
