Abstract:In this paper we study the set of statistical cluster points of sequences in m-dimensional spaces. We show that some properties of the set of statistical cluster points of the real number sequences remain in force for the sequences in m-dimensional spaces too. We also define a notion of Gamma-statistical convergence. A sequence xis Gamma-statistically convergent to a set Cif Cis a minimal closed set such that for every isin > 0 the set 
$$\{ k:\varrho (C,x_{{\text{ }}k} ) \geqslant \varepsilon \} $$
has density zero. It is shown that every statistically bounded sequence is Gamma-statistically convergent. Moreover if a sequence is Gamma-statistically convergent then the limit set is a set of statistical cluster points.
Keywords:compact sets  natural density  statistically bounded sequence  statistical cluster point
