On a generalization of Appell*s functions of two variables

Resumen

The present paper introduces 10 Appell's type generalized functions M?, i = 1, 2, ... , 10 by considering the product of two 3F2 functions instead of product of two Gauss functions taken by Appell to define F1, F2 , F3 and F4 functions. In the concluding remark it has been pointed out that by considering the product of two nFn-1 functions a set of n² + n- 2 functions analogus to Appell functions will emerge. The paper contains fractional derivative representations, integral representations, symbolic forms and expansion formulae similar to those obtained by Burchnall and Chaundy for the four Appell's functions, have been obtained for these newly defined functions M1, M2 , … M10.
