Paranorm I-convergent sequence spacesAbstract
In this article we introduced the sequence spaces c
I(p), c
0I(p), m
I(p) and m
0I(p) for p = (p
k), a sequence of positive real numbers. We study some algebraic and topological properties of these spaces. We prove the deco... ...

Generalized q-Baskakov operatorsAbstract
In the present paper we propose a generalization of the Baskakov operators, based on q integers. We also estimate the rate of convergence in the weighted norm. In the last section, we study some shape preserving properties and the property of monotonicity of q-Baskakov operators.

$\bar \lambda $-statistically convergent double sequences in probabilistic normed spacesAbstract
The purpose of this paper is to introduce and study the concepts of double $\bar \lambda $-statistically convergent and double $\bar \lambda $-statistically Cauchy sequences in probabilistic normed space.

A gould type integral with respect to a multisubmeasureAbstract
In [GOULD, G. G.: Integration over vector-valued measures, Proc. London Math. Soc. (3) 15, (1965), 193–205], G. G. Gould introduced a type of integral of a bounded, real valued function with respect to a finite additive set function taking values in a Banach space, integral which is more general than the Lebesgue one. Recently, A. Precupanu ... ...

Some topological and geometric properties of generalized Euler sequence spaceAbstract
In this paper, we introduce the Euler sequence space e
r(p) of nonabsolute type and prove that the spaces e
r(p) and l(p) are linearly isomorphic. Besides this, we compute the α-, β- and γ-duals of the space e
r(p). The results proved herein are analogous to those in [AL... ...

Companion d-algebrasAbstract
In this paper we develop a theory of companion d-algebras in sufficient detail to demonstrate considerable parallelism with the theory of BCK-algebras as well as obtaining a collection of results of a novel type. Included among the latter are results on certain natural posets associated with companion d-algebras as well as constructions on B... ...

Dynamic effect algebrasAbstract
We introduce the so-called tense operators in lattice effect algebras. Tense operators express the quantifiers “it is always going to be the case that” and “it has always been the case that” and hence enable us to express the dimension of time in the logic of quantum mechanics. We present an axiomatization of these tense operators and prove ... ...

The shifted Gompertz-G family of distributions: Properties and applicationsAbstract
This article proposes a class of generator for classical statistical distribution called the shifted Gompertz-G (SHIGO-G) distribution for generating new continuous distributions. Special models of the proposed model were examined together with some of its statistical properties in closed form which makes it tractable for censored data. Its ... ...

Symmetries in synaptic algebrasAbstract
A synaptic algebra is a generalization of the Jordan algebra of self-adjoint elements of a von Neumann algebra. We study symmetries in synaptic algebras, i.e., elements whose square is the unit element, and we investigate the equivalence relation on the projection lattice of the algebra induced by finite sequences of symmetries. In case the ... ...

The general gould type integral with respect to a multisubmeasureAbstract
In two earlier papers [GAVRILUŢ, A.: A Gould type integral with respect to a multisubmeasure, Math. Slovaca 58 (2008), 1–20] and [Gavriluţ, A.: On some properties of the Gould type integral with respect to a multisubmeasure, An. Ştiinţ. Univ. Al. I. Cuza Iaşi. Mat. (N.S.) 52 (2006), 177–194], we defined and studied a Gould type integral for ... ...
