Solvability of (P,Q)-functional integral equations of fractional order using generalized Darbo’s fixed point theorem

open access: yesFilomat, 2023
In this article, we establish a generalized version of Darbo?s fixed point theorem via some newly defined condensing operators and we define a new fractional integral using (P,Q)-calculus and study its properties. Finally, we apply this generalized Darbo?s fixed point theorem to check the existence of a solution of (P,Q)- functional ...
