Abstract

Analysis Article general Mathematical Methods in Physics Mathematics Mathematics and Statistics
We prove a fixed point result for nonlinear operators, acting on some classes of functions with values in a dq-metric space, and show some applications of it. The result has been motivated by some issues arising in Ulam stability. We use a restricted form of a contraction condition.
