Inequalities concerning the (p,k)-gamma and (p,k)-polygamma functions


In this paper, we establish several inequalities involving the (p,k)-gamma and (p,k)-polygamma functions. Among other tools, we employ the mean value therorem, the Hermite-Hadamard's inequality, Petrovic's inequality and the Holder's inequality. Upon some parameter variations, we recover some known results as special cases of the established results.
