In this manuscript, we introduce the (Ψ,Φ)-orthogonal interpolative contraction as a generalization of an orthogonal interpolative contraction. We prove several fixed point theorems stating conditions under which (Ψ,Φ)-orthogonal interpolative contraction admits a fixed point. Our fixed point results are improvements of several known results in literature. As an application, we resolve a fractional differential equation.

Keywords: fixed point, (Ψ, Φ)-orthogonal interpolative contractions, complete O-metric space, application
