New fixed point results in rectangular metric space and application to fractional calculus

Abstract

In this paper, we introduce alpha - psi type contractive mapping in rectangular metric space satisfying certain admissibility conditions and prove a fixed point result for such mapping in complete and Hausdorff rectangular metric space. Some examples are given to justify our result. Also we have shown that the existence of solution of a nonlinear fractional differential equation can he guaranteed, as an application of our result.
