Y. Mizuta, INTEGRAL-REPRESENTATIONS, DIFFERENTIABILITY PROPERTIES AND LIMITS AT INFINITY FOR BEPPO-LEVI FUNCTIONS, Potential analysis, 6(3), 1997, pp. 237-267
The first aim in the present paper is to give an integral representati
on for Beppo Levi functions on R-n. Our integral representation is an
extension of Sobolev's integral representation given for infinitely di
fferentiable functions with compact support. As applications, continui
ty and differentiability properties of Beppo Levi functions are studie
d. Our second aim in this paper is to study the existence of limits at
infinity for Beppo Levi functions. We also consider the existence of
fine-type limits at infinity with respect to Bessel capacities, which
yields the radial limit result at infinity.
