Abstract We deal with the existence and localization of positive radial solutions for Dirichlet problems involving \(\phi\)-Laplacian operators in a…

AbstractThe paper deals with semilinear operator equations involving iterates of a strongly monotone symmetric linear operator. In particular there are…

Abstract We establish compression-expansion type fixed point theorems for systems of operator inclusions with decomposable multivalued maps. The approach is…

Abstract The aim of this paper is to draw attention to a general principle for solving control problems for operator…

AbstractIn this paper, the operator approach based on the fixed point principles of Banach and Schaefer is used to establish…
