Some typical generating relations for these extended hypergeometric functions are obtained by defining the extension of the Riemann-Liouville fractional derivative operator. Their connections with elementary functions and Fox’s H-function are also presented PB De Gruyter YR 2017 FD 2017 LK http://hdl.handle.net/10347/17585 UL http://hdl.handle.net/10347/17585 LA eng NO Agarwal, P., Nieto, J.J., Luo, M.-J.
