Journal Title: JOURNAL OF ADVANCES IN MATHEMATICS - Year 2017, Vol 13, Issue 4
Abstract
The.main.aim of our paper is introduced.new.conceptofcompactspaceis called wb-compact.Space, for this aim, the concept of b-compact space and w-compact space introduced and find that every is relationships among compact, b-compact, w-compact spaces and the converse is not not true in generals and we define nearly ? b-compact space and we prove some results about subject.

Some Universal Constructions For I- Fuzzy Topological Spaces II
Hamouda E. H. [J. of Advances in Math. Vol 6 (2014), 973-941] has introduced some universal constructions in the category FTOP, whose objects are the I-fuzzy topological spaces(x,,F) where X is an ordinary set, is a fuzz...
Rational Chebyshev functions with new collocation points in semi-infinite domains for solving higher-order linear ordinary differential equations
The purpose of this paper is to investigate the use of rational Chebyshev (RC) functions for solving higher-order linear ordinary differential equations with variable coefficients on a semi-infinite domain using new rati...

SS-Coprime Modules
Let R be a commutative ring with unity and M is a unitary left R-module . In this paper , we introduce the notion of strongly S-coprime modules, where M is called strongly S-coprime briefly (SS-Coprime) if for each r R ,...
