Item type:Article, Access status: Open Access , On a new critical point theorem and some applications to discrete equations(2014) Galewski, Marek; Galewska, ElżbietaUsing the Fenchel-Young duality we derive a new critical point theorem. We illustrate our results with solvability for certain discrete BVP. Multiple solutions are also considered.
