    Agnieszka Kałamajska (University of Warsaw): Extension theorems dealing with weighted Orlicz-Slobodetskii space. Abstract: We discuss trace extension theorems between weighted Orlicz-Sobolev spaces of functions defined on bounded domain Omega in R^n and weighted Orlicz-Slobodetski spaces of functions defined on the boundary of Omega. This gives a new tool to deal with inhomogeneous boundary value problems for degenerate elliptic PDEs.

    (1) Luca Vilasi (University of Messina): Half Laplacian equations in bounded domains. Abstract: In this seminar I will focus on a fractional elliptic equation governed by the half Laplacian in a smooth bounded domain of Rn and with Dirichlet conditions on the boundary. By assuming a suitable growth of the nonlinearity in addition to some (technical) algebraic conditions, I will show the existence of at least three L1-bounded weak solutions. My approach relies upon Caffarelli-Silvestre's extension method and some variational methods for smooth functionals defined on reflexive Banach spaces.

    (2) Marek Galewski (Politechnika Lodzka): On a global implicit function theorem for locally Lipschitz mappings in finite dimensional spaces. Abstract: This talk is based on our joint research with Marius Radulescu. We concentrate on providing conditions under which a locally Lipschitz mapping F:E->E, where E is a finite dimensional Euclidean space, is a diffeomorphism. Next, we generalize this result to get a global implicit function theorem. Applications to algebraic equations are given. On a global invertibility of locally Lipschitz mappings on R^n.

    (3) Michał Beldzinski (Politechnika Lodzka): Application of a global diffeomorphism theorem to the solvability of abstract equations.
