Abstract

In this paper, we present a generalization of Euler’s identity associated to usual hypergeometric function in the form of an identity associated with the k-hypergeometric function. The second-order homogeneous k-hypergeometric differential equation , by Frobenious method yields a pair {y₁(z),y₂(z)} of linearly independent solutions in the form of k-hypergeometric function 2F1,k define as k-hypergeometric power series is convergent in the region ={z: |z|<1/k}. Here with suitable substitution to y(z), we deduce two other forms of solutions of this equation near the singularity z=0. Using the dependency of these forms on {y₁(z),y₂(z)}, we obtain the generalized Euler’s identity in the form of k-hypergeometric function and a new k-hypergeometric transformation formula. Our generalization pertains to the case when the generalized Euler’s identity reduced to the classical Euler’s identity. In the ultimate section of the paper, we obtain another reduction formula for a particular product difference of k-hypergeometric functions.
