Mathematics Department, University of Alabama Box 870350, Tuscaloosa, Alabama 35487-0350, USA
The purpose of this paper is to give necessary and sufficient conditions for the boundedness from
(R+) to
of Volterra convolution operators of the form
, where k(x) is a non-negative non-decreasing kernel satisfying k(x+y)
D(k(x)+k(y)) for all x, y
R+. The cases of 1 < p,q <
and 0 < q < 1 < p <
are considered. Also criteria for the compactness of K for 1 < p, q <
are given.
