, 2011 A graph that has a Smarandachely vertex-mean k-labeling is called Smarandachely k vertex-mean graph or Smarandachely k V -mean graph. Particularly, if k = 0, such a Smarandachely vertex-mean 0-labeling and Smarandachely 0 vertex-mean graph or ...

Vertex maps on graphs – Perron–Frobenius theory [PDF]
Journal of Difference Equations and Applications, 2015 The goal of this paper is to describe the connections between Perron-Frobenius theory and vertex maps on graphs. In particular, it is shown how Perron-Frobenius theory gives results about the sets of integers that can arise as periods of periodic orbits, about the concepts of transitivity and topological mixing, and about horseshoes and topological ...

Mathematical Gazette, 1973 In graph theory, the term graph refers to a set of vertices and a set of edges. A vertex can be used to represent any object. Graphs may contain undirected or directed edges. An undirected edge is a set of two vertices. A directed edge is an ordered pair

Crown reductions for the Minimum Weighted Vertex Cover problem [PDF]
, 2004 The paper studies crown reductions for the Minimum Weighted Vertex Cover problem introduced recently in the unweighted case by Fellows et al. [Blow-Ups, Win/Win's and crown rules: some new directions in FPT, in: Proceedings of the 29th International ...

Parameterized streaming : maximal matching and vertex cover [PDF]
, 2014 As graphs continue to grow in size, we seek ways to effectively process such data at scale. The model of streaming graph processing, in which a compact summary is maintained as each edge insertion/deletion is observed, is an attractive one.

Some topological indices of pentagonal double chains [PDF]
ITM Web of Conferences, 2022 In graph theory, lattices are used when some structural part of the graph repeats itself finitely or infinitely many times. They have applications in complex analysis and geometry in mathematics, and also natural applications in chemical graph theory. As

3-degenerate induced subgraph of a planar graph [PDF]
, 2021 A graph $G$ is $d$-degenerate if every non-null subgraph of $G$ has a vertex of degree at most $d$. We prove that every $n$-vertex planar graph has a $3$-degenerate induced subgraph of order at least $3n/4$.Comment: 28 pages, 12 ...

Complex fermatean neutrosophic graph and application to decision making
Decision Making: Applications in Management and Engineering, 2023 A new growing area of neutrosophic set (NS) theory called complex neutrosophic sets (CNS) provides useful tools for dealing with uncertainty in complex valued physical variables that are observed in the actual world.

Vertex and edge covers with clustering properties: complexity and algorithms [PDF]
, 2009 We consider the concepts of a t-total vertex cover and a t-total edge cover (t≥1), which generalise the notions of a vertex cover and an edge cover, respectively.
