Abstract

We provide sufficient conditions under which the set of common fixed points of two self-mappings \(f, g : X \rightarrow X\) is nonempty, and every common fixed point of f and g is the zero of a given function \(\varphi:X \rightarrow [0,\infty)\). Next, we show the usefulness of our obtained result in partial metric fixed point theory.
