    Conditions for having a diffeomorphism between two Banach spaces
    (Department of Mathematics - Texas State University, 2014) Galewski, Marek; Galewska, Elżbieta; Schmeidel, Ewa
    We provide sufficient conditions for a mapping acting between two Banach spaces to be a diffeomorphism. Standart arguments allow us to obtain a local diffeomorphism. It is proved to be global using mountain pass geometry.

    On a new critical point theorem and some applications to discrete equations
    (AGH University of Science and Technology Press, 2014) Galewski, Marek; Galewska, Elżbieta
    Using 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.
