New concepts on level graphs of vague graphs with application in medicine
Frontiers in Physics, 2023 Vague graphs (VGs), belonging to the fuzzy graph (FG) family, have good capabilities when facing problems that cannot be expressed by FGs. When an element membership is unclear, neutrality is a good option that can be well-supported by a VG. The previous

New Concepts of Picture Fuzzy Graphs with Application
Mathematics, 2019 The picture fuzzy set is an efficient mathematical model to deal with uncertain real life problems, in which a intuitionistic fuzzy set may fail to reveal satisfactory results.

Total irregularity strength for product of two paths
AKCE International Journal of Graphs and Combinatorics, 2020 In this paper we define a totally irregular total labeling for Cartesian and strong product of two paths, which is at the same time vertex irregular total labeling and also edge irregular total labeling.

Algebras of Binary Isolating Formulas for Strong Product Theories
Известия Иркутского государственного университета: Серия "Математика", 2023 Algebras of distributions of binary isolating and semi-isolating formulas are objects that are derived for a given theory, and they specify the relations between binary formulas of the theory.

Strong geodetic problem on Cartesian products of graphs [PDF]
, 2017 The strong geodetic problem is a recent variation of the geodetic problem. For a graph $G$, its strong geodetic number ${\rm sg}(G)$ is the cardinality of a smallest vertex subset $S$, such that each vertex of $G$ lies on a fixed shortest path between a ...

Products of Strong Świa̧tkowski Functions [PDF]
Journal of Applied Analysis, 2006 A function \(f\) is said to be a strong Świątkowski function if whenever \(\alpha , \beta \in I\) and \( y \in I(f(\alpha),f(\beta))\), there is an \(x_0 \in I(\alpha,\beta) \cap C(f)\) such that \(f(x_0) = y\) where \(I\) is a nondegenerate interval, \(I(a,b) = (a,b)\) if \(a < b\) and \((b,a)\) otherwise and \(C(f)\) denotes the set of all points of ...

Market size, competition, and the product mix of exporters [PDF]
, 2010 We build a theoretical model of multi-product firms that highlights how competition across market destinations affects both a firm's exported product range and product mix.

Strong Anxiety Boosts New Product Adoption When Hope Is Also Strong [PDF]
Journal of Marketing, 2020 New products can evoke anticipatory emotions such as hope and anxiety. On the one hand, consumers might hope that innovative offerings will produce goal-congruent outcomes; on the other hand, they might also be anxious about possible outcomes that are goal-incongruent.

Spectrum and Ricci Curvature on the Weighted Strong Product Graphs
IEEE Access, 2023 The strong product on graphs is also called the normal product or the AND product. It is the union of Cartesian product and tensor product, and also is a binary operation on graphs. This operation takes two graphs and produces a new graph. In this paper,

Journal of Combinatorial Theory, Series A, 1994 The paper obtains algebraic structure theorems and properties for the strong Kronecker product of two block matrices, \(M= [M_{ij}]\) and \(N= [N_{jk}]\), where \(i= 1,\dots,r\), \(j= 1,\dots,t\), \(k= 1,\dots,u\), each \(M_{ij}\) is an \(m\times p\) submatrix, each \(N_{jk}\) is an \(n\times q\) matrix, namely: \(M\circ N= [L_{ik}]\), \(i= 1,\dots,r\),
