multivalued orthogonal ℱ‐contraction mappings in the framework of orthogonal metric
spaces. As a consequence of results, we obtain some interesting results. Also as application
of the results obtained, we investigate Ulam's stability of fixed point problem and present a
solution for the Caputo‐type nonlinear fractional integro‐differential equation. An example is
also provided to illustrate the usability of the obtained results.
