Fuzzy Graph Structures with Application
Mathematics, 2019 In this article, we introduce the notions of maximal products of fuzzy graph structures, regular fuzzy graph structures, and describe these notions with examples and properties.

On the chromatic number of graphs with some restriction of vertex degrees
Учёные записки Казанского университета: Серия Физико-математические науки, 2020 Graphs, for which the degree of a certain vertex is equal to (d + 1) and the degrees of all other vertices are at most d , d ≥ 3 , were considered. Properties were obtained to color vertices of these graphs in d colors.

PREFERENTIAL ATTACHMENT WITH FITNESS DEPENDENT CHOICE
Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2021 We study the asymptotic behavior of the maximum degree in the preferential attachment tree model with a choice based on both the degree and fitness of a vertex.

On Extended Adjacency Index with Respect to Acyclic, Unicyclic and Bicyclic Graphs
Mathematics, 2019 For a (molecular) graph G, the extended adjacency index E A ( G ) is defined as Equation (1). In this paper we introduce some graph transformations which increase or decrease the extended adjacency ( E A ) index.

Reformulated Zagreb Indices of Some Derived Graphs
Mathematics, 2019 A topological index is a numeric quantity that is closely related to the chemical constitution to establish the correlation of its chemical structure with chemical reactivity or physical properties.

Usefulness of Combinations of Vertex-Degree Weighted Path Indices and Elements of a Universal Matrix
Acta Chimica Slovenica, 2019 The mutually optimized combinations of vertex-degree weighted path indices and the vertex-degree vertex-distance weighted elements of the Universal matrix were applied in the way of TInew = ∑kN×PN(aN,bN,...) + kij×uij(aij,bij,cij).

Cost-based analyses of random neighbor and derived sampling methods
Applied Network Science, 2022 Random neighbor sampling, or RN, is a method for sampling vertices with a mean degree greater than that of the graph. Instead of naïvely sampling a vertex from a graph and retaining it (‘random vertex’ or RV), a neighbor of the vertex is selected instead.

On single-valued co-neutrosophic graphs [PDF]
Neutrosophic Sets and Systems, 2018 In this paper, we introduce the notion of a single-valued co-neutrosophic graphs and study some methods of construction of new single-valued co-neutrosophic graphs.
