Some new lacunary -statistical -convergent sequence spaces of order
We study the concept of density for sets of natural numbers in some lacunary
-convergent sequence spaces. Also we are trying to investigate some relation
between the ordinary convergence and module statistical convergence for evey
unbounded modulus function. Morever we also study some results on the newly
defined lacunary -statistically -convergent sequence spaces with respect
to some Musielak-Orlicz function.Comment: Conference paper. arXiv admin note: text overlap with

Upward and downward statistical continuities
A real valued function defined on a subset of , the set
of real numbers, is statistically upward continuous if it preserves
statistically upward half quasi-Cauchy sequences, is statistically downward
continuous if it preserves statistically downward half quasi-Cauchy sequences;
and a subset of , is statistically upward compact if any
sequence of points in has a statistically upward half quasi-Cauchy
subsequence, is statistically downward compact if any sequence of points in
has a statistically downward half quasi-Cauchy subsequence where a sequence
of points in is called statistically upward half
quasi-Cauchy if is statistically downward half
quasi-Cauchy if for every . We investigate
statistically upward continuity, statistically downward continuity,
statistically upward half compactness, statistically downward half compactness
and prove interesting theorems. It turns out that uniform limit of a sequence
of statistically upward continuous functions is statistically upward
continuous, and uniform limit of a sequence of statistically downward
continuous functions is statistically downward continuous.Comment: 25 pages. arXiv admin note: substantial text overlap with

ON GENERALIZED STATISTICAL CONVERGENCE OF DOUBLE SEQUENCES VIA IDEALS IN INTUITIONISTIC FUZZY NORMED SPACES
In this paper, we introduce the concept of I₂-lacunary statistical convergence and strongly I₂-lacunary convergence with respect to the intuitionistic fuzzy norm (μ,v), investigate their relationship, and make some observations about these classes. We mainly examine the relation between these two new methods and the relation between I₂-statistical convergence in the corresponding intuitionistic fuzzy normed space
On fuzzy real-valued double A-sequence spaces defined by Orlicz function
The purpose of this paper is to introduce and study a new concept of
strong fuzzy real-valued double A- convergence sequences with respect to an Orlicz function. Also, some
properties of the resulting fuzzy real-valued sequence spaces are
examined. In addition, we define
the double A-statistical convergence and
establish some connections between the spaces of strong double
A-convergence sequence and double -statistical convergence sequence
