In this paper we introduce certain new sequence spaces of fuzzy numbers defined by I-convergence using sequences of Orlicz functions and a difference operator of order m. We study some basic topological and algebraic properties of these spaces. Also we investigate the relations related to these spaces. © 2011 Elsevier Ltd. Source

In this paper we introduce a new concept for lacunary strong P-convergent with respect to an Orlicz function and examine some properties of the resulting sequence space of fuzzy numbers. We also show that if a sequence is lacunary s rong Pconvergence with respect to an Orlicz function then it is, S θr,s F-convergent. © Association for Scientific Research. Source

Quite recently, Savaş (Appl Math Lett 21:134-141, 2008), defined the lacunary statistical analogue for double sequence X = {X k,l} of fuzzy numbers as follows: a double sequence X = {X k,l} is said to be lacunary P-statistically convergent to X 0 provided that for each ε > 0, In this paper we introduce and study double lacunary σ-statistical convergence for sequence of fuzzy numbers and also we get some inclusion theorems. © 2011 Springer-Verlag.

In this paper we prove new complete monotonicity properties of some functions involving the gamma function. As consequences of them we establish various new upper and lower bounds for the gamma function and the harmonic numbers. © 2011 Elsevier Ltd. Source

The aim of this paper is to introduce and study a new concept of strong double (A)Δ-convergent sequence of fuzzy numbers with respect to an Orlicz function and also some properties of the resulting sequence spaces of fuzzy numbers are examined. In addition, we define the double (A, Δ)-statistical convergence of fuzzy numbers and establish some connections between the spaces of strong double (A)Δ-convergent sequence and double (A, Δ)-statistical convergent sequence.
