By Sobolev's imbedding theorem, we know that if / is a nonnegative function in L(R) satisfying (1.1), and if αp > n, then Uaf is continuous at the origin (in fact, on Rn)'9 however, in case oφ < n, Uaf may fail to be continuous at the origin. Thus, our main concern in this paper is the bordering case p = n/α, and one of our aims is to find a condition on /, which is stronger than the condition that feL(R) with p = n/α but assures the continuity at 0 of UΛf. For this purpose, we assume that / satisfies a condition of the form:
