“…Recently, by applying the following definition of a fractional differintegral (that is, fractional derivative and fractional integral) of order u E R, many authors have explicitly obtained particular solutions of a number of families of homogeneous (as well as nonhomogeneous) linear ordinary and partial fractional differintegral equations (see, for details, [5][6][7][8][9][10][11][12][13][14][15][16][17][18], and the references cited in each of these earlier works). [19][20][21] for c-, (1.4) for c +, (1.5) then f~(z) ( First of all, we find it to be worthwhile to recall here the following potentially useful lemmas and properties associated with the fractional differintegration which is defined above (cf., e.g., [19,20]).…”
