amonge other things we give sufficient and necessary conditions for the lau product of banachalgebras to be biflat or biprojective.

Software Product Line Engineering (SPLE) promotes the development and maintenance of artifacts that can be reused in families of related software-intensive systems. As product lines are not necessarily disjoint and the development of product line artifacts is a demanding task, utilization of “related” or “similar” product line artifacts for creating or improving the artifacts of a particular pr...

New product development (NPD) is described in the literature as the transformation of a market opportunity into a product available for sale. In the automotive industry, within the context of ISO/TS16949:2002 (the automotive quality management system international standard),  these related to the product realization process (PRP) which consists of Three main phases such as planning, Implem...

in this paper, we give a characterization of strongly jordan zero-product preserving maps on normed algebras as a generalization of  jordan zero-product preserving maps. in this direction, we give some illustrative examples to show that the notions of strongly zero-product preserving maps and strongly jordan zero-product preserving maps are completely different. also, we prove that the direct p...

Over the last decade, the retail industry has had a phenomenal growth. All figures show their success and efficiency and many studies have shown the role of customer reviews in encouraging ambivalent purchasers to buy items online. There have been numerous studies on why people read and trust these comments and taking for granted the important role of customer reviews in determining buying deci...

let g be a simple connected graph. the generalized polarity wiener index ofg is defined as the number of unordered pairs of vertices of g whosedistance is k. some formulas are obtained for computing the generalizedpolarity wiener index of the cartesian product and the tensor product ofgraphs in this article.
