Fixed Point Theorems for a Class of α-Admissible Contractions and Applications to Boundary Value Problem

الملخص EN

A class of α-admissible contractions defined via altering distance functions is introduced.

The existence and uniqueness conditions for fixed points of such maps on complete metric spaces are investigated and related fixed point theorems are presented.

The results are reconsidered in the context of partially ordered metric spaces and applied to boundary value problems for differential equations with periodic boundary conditions.
