Query: On hypergeometric functions and Pochhammer $k$-symbol   We introduce the $k$-generalized gamma function $\Gamma_k$, beta function
$B_k$, and Pochhammer $k$-symbol $(x)_{n,k}$. We prove several identities
generalizing those satisfied by the classical gamma function, beta function and
Pochhammer symbol. We provided integral representation for the $\Gamma_k$ and
$B_k$ functions.
