In this paper we present some basic results on the generalized Lebesgue spa
ces L-p(x)(Omega) and generalized Lebesgue-Sobolev spaces W-m,W-p(x)(Omega)
. These results provide the necessary framework for the study of variationa
l problems and elliptic equations with non-standard p(x)-growth conditions.
