FRACTIONAL DERIVATIVES AND EXPANSION FORMULAS INVOLVING H-FUNCTIONS OF ONE AND MORE VARIABLES

Certain general fractional derivatives formulas involving the EI-funct ion of one and more variables are established that generalize the corr esponding results considered by Srivastava and Goyal. This leads us to an extension of the expansion formula for the Lauricella function F-D ((r)) given by Srivastava and Goyal. Various other analogous formulas are also established. These results are significantly different from B urchnall and Chaundy-type expansions. (C) 1997 Academic Press.
