A characterization of holomorphic bivariate functions of bounded index [PDF]

, 2017
The following notion of bounded index for complex entire functions was presented by Lepson. function f(z) is of bounded index if there exists an integer N independent of z, such that The main goal of this paper is extend this notion to holomorphic ...

Invariant means and lacunary sequence spaces of order (α, β)

Demonstratio Mathematica
In this article, we use the notion of lacunary statistical convergence of order (α,β)\left(\alpha ,\beta ) to introduce new sequence spaces by lacunary sequence, invariant means defined by Musielak-Orlicz function ℳ=(ℵk){\mathcal{ {\mathcal M} }}=\left({\

Lacunary statistical convergence of double sequences [PDF]

, 2005
In 1978 Freedman, Sember, and Raphael presented a definition for lacunary refinement as follows: $rho={bar{k}_{r}}$ is called a lacunary refinement of the lacunary sequence $theta ={k_{r}}$ if ${k_{r}}subseteq {bar{k}_{r}}$.

Optimization and matrix constructions for classification of data [PDF]

, 2011
Max-plus algebras and more general semirings have many useful applications and have been actively investigated. On the other hand, structural matrix rings are also well known and have been considered by many authors.

RH-regular transformation of unbounded double sequences [PDF]

, 2013
At the Ithaca meeting in 1946 it was conjectured that it is possible to construct a two-dimensional regular summability matrix $A=\{a_{n,k}\}$ with the property that, for every real sequence $\{s_{k}\}$, the transformed sequence $$t_{n}=\sum_{k=0 ...

Approving the ISDWIR method of risk measurement in making risk management decision [PDF]

, 2014
This paper is devoted to risk management and risk measurement methods. The author considers methods of risk measurement and proposes the Inte- gral Sum of Differential Weighted Indexes of Risks (or ISDWIR) method of risk measurement.

Generalized lacunary strong Zweier convergent sequence spaces [PDF]

, 2016
In this paper we introduce generalized double Zweier lacunary convergent sequence spaces via sequence of Orlicz functions over n-normed spaces. We also make an effort to study some topological properties and inclusion relations between these spaces ...

E-core of double sequences [PDF]

, 2014
Boos, Leiger and Zeller [1,2] defined the concept of e-convergence. In this paper we introduce the concepts of e-limit superior and inferior for real double sequences and prove some fundamental properties of e-limit superior and inferior.

Some classes of matrix transforms related to speed-Maddox spaces over ultrametric fields [PDF]

Let K be a complete, non-trivially valued, ultrametric (or non-archimedean) field, and λ = {λn} − a sequence in K with the property 0 < |λn| ↗ ∞, n ➝ ∞, i.e., the speed of convergence.
