Complex Vague Graphs and Their Application in Decision-Making Problems
IEEE Access, 2020 Fuzzy graph models are found everywhere in natural and human made structures, including process dynamics in biological, physical and social systems. Since real-life problems are often uncertain due to inconsistent and indeterminate information, it is ...

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

Strong Products of Hypergraphs: Unique Prime Factorization Theorems and Algorithms [PDF]
, 2013 It is well-known that all finite connected graphs have a unique prime factor decomposition (PFD) with respect to the strong graph product which can be computed in polynomial time.

On bounds for topological descriptors of φ-sum graphs
Journal of Taibah University for Science, 2020 The properties of chemical compounds are very important for the studies of the non-isomorphism phenomenon's related to the molecular graphs. Topological indices (TIs) are one of the mathematical tools which are used to study these properties.

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.

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 ...

Implementation issues in product line scoping [PDF]
, 2000 Often product line engineering is treated similar to the waterfall model in traditional software engineering, i.e., the different phases (scoping, analysis, architecting, implementation) are treated as if they could be clearly separated and would follow ...

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.

Harary Index of Product Graphs
Discussiones Mathematicae Graph Theory, 2015 The Harary index is defined as the sum of reciprocals of distances between all pairs of vertices of a connected graph. In this paper, the exact formulae for the Harary indices of tensor product G × Km0,m1,...,mr−1 and the strong product G⊠Km0,m1,...,mr−1

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,
