Aa. Kilbas et M. Saigo, SOLUTION OF ABEL INTEGRAL-EQUATIONS OF TH E 2ND KIND AND DIFFERENTIAL-EQUATIONS OF FRACTIONAL ORDER, Doklady Akademii nauk BSSR, 39(5), 1995, pp. 29-34
Solutions of new classes of nonhomogeneous Abel integral equations of
the second kind and nonhomogeneous differential equations of fractiona
l order with quasipolynomial free terms are given. Full systems of lin
ear independent solutions of corresponding homogeneous differential eq
uations of fractional order and, in particular, of ordinary differenti
al equations are constructed. Solutions obtained are expressed in term
s of special functions which generalize classical Mittag-Leffler funct
ions.
