Introduction. Recently there have appeared papers ([7], [8]; also see [9] ) in which integral equations with kernels involving the confluent hypergeometric function i F i ( a ; c ; z ) = Aw:^' where {a)n= have been studied. These equations are mainly Volterra equations of the first kind except that they have infinite domain (0, °°). The rest are of the related type with integrals over (x, °°) instead of (0, x); and all are convolution equations. The equation solved in this paper is a Fredholm

Formally the relationship of this equation to those in [7] and [8] is similar to that of the equation in [5] to those in [3] and [4]. However, the equations in [3], [4] and [5] have Gauss's hypergeometric function 2 Fi in place of the confluent function. Preliminary work on the Weyl fractional integral and derivative is set out in § §2 and 3. This augments the treatments given in [4] and [6], neither of which is adequate for the present purpose. Weyl Fractional Integrals. We use the customary definition D n J"f{x) = J v D n f{x).
