The purpose of this paper is to introduce two new spaces and also to define st(sigma) and st(0sigma) of strongly sigma-statistically convergent and lacunary strongly sigma-statistically convergent sequences, respectively. Also, we give some inclusion relations involving these spaces. (C) 2003 Elsevier Inc. All rights reserved.
