Some new spaces of lacunary ƒ-statistical A-convergent sequences of order α.

We study the concept of density for sets of natural numbers in some spaces of lacunary A-convergent sequences. Also we investigate the relation between the ordinary convergence and module statistical convergence for every unbounded modulus function. Morever we also study some results on the spaces of lacunary ƒ-statistically A-convergent sequences with respect to some Musielak-Orlicz function. [ABSTRACT FROM AUTHOR]
