Aikawa, Hiroaki (ed.) et al., Potential theory in Matsue. Selected papers of the international workshop on potential theory, Matsue, Japan, August 23–28, 2004. Tokyo: Mathematical Society of Japan (ISBN 4-931469-33-7/hbk). Advanced Studies in Pure Mathematics 44, 255-281 (2006).
The aim of this paper is to deal with the boundedness of maximal functions in Lebesgue spaces $$L^{p(\cdot)}$$ with variable exponent $$p(\cdot)$$. As an application of the boundedness of maximal functions the authors show Sobolev’s inequality for Riesz potentials with variable exponent.
