# A Note on \(K_4\) Fractional Integral Operator

## Abstract

The present paper deals with the study of new generalized fractional integral operator involving \(K_4\)-function due to Sharma. Mellin and Laplace transforms of this new operator are investigated. The bounded-ness and composition properties of the proposed operator are also established. Further, derived results are applied to solve fractional differential equation involving \(K_4\)-function associated with Hilfer derivatives. The \(K_4\)-function is further extension of *M*-series and the importance of desired results lies in the fact that many known results are readily follows as special cases of our finding. \(K_4\) and *M*-series have recently found essential application in solving problems of science, engineering and technology. Some special cases of the established results are given in form of corollaries.
