Abstract: We prove a fixed point theorem for nonlinear operators, acting on some function spaces (of set-valued maps), which satisfy suitable inclusions. We also show some applications of it in the Ulam type stability. read more here.

Abstract: In this paper we investigate autonomous as well as nonautonomous superposition operators acting between spaces of functions of bounded $$\Lambda $$Λ-variation. A particular emphasis is put on acting conditions as well as on continuity problems… read more here.
