Recent Trends on Ulam–Hyers Stability Results of Fixed Point Problems

Abstract

Fixed point theorems have been extensively used in recent years to prove the Ulam–Hyers stability results of functional equations. In this chapter, we collect novel Ulam–Hyers stability results obtained by using well-known fixed point theorems in the setting of a complete metric space. We focus on several types of functional equations and inclusions along with some applications on the stability of the specific integral and differential equation. © 2026 by World Scientific Publishing Co.
