By introducing the notions of L-spaces and L_r-spaces, a complete generalization of Kalton’s closed graph theorem is obtained. It points out the class of L_r-s
In this paper, we study the following eigenvalue problem involving limiting nonlinearity by a new way of using the concentration-compactness principle. Even in
In this paper the existence of random solutions of operator equations with A-proper Operators is studied. The random analog of deterministic results obtained by
