Constructing vertex decomposable graphs
Recently, some techniques such as adding whiskers and attaching graphs to vertices of a given graph, have been proposed for constructing a new vertex decomposable graph. In this paper, we present a new method for constructing vertex decomposable graphs. Then we use this construction to generalize the result due to Cook and Nagel.
متن کاملThe robust vertex centdian location problem with interval vertex weights on general graphs
In this paper, the robust vertex centdian location problem with uncertain vertex weights on general graphs is studied. The used criterion to solve the problem is the min-max regret criterion. This problem is investigated with objective function contains $lambda$ and a polynomial time algorithm for the problem is presented. It is shown that the vertex centdian problem on general graphs i...
متن کاملOn discriminativity of vertex-degree-based indices
A recently published paper [T. Došlić, this journal 3 (2012) 25-34] considers the Zagreb indices of benzenoid systems, and points out their low discriminativity. We show that analogous results hold for a variety of vertex-degree-based molecular structure descriptors that are being studied in contemporary mathematical chemistry. We also show that these results are straightforwardly obtained by u...

The notions of vertex Lie algebra and vertex Poisson algebra are presented and connections among vertex Lie algebras, vertex Poisson algebras and vertex algebras are discussed.
متن کاملVertex algebras and vertex poisson algebras
This paper studies certain relations among vertex algebras, vertex Lie algebras and vertex poisson algebras. In this paper, the notions of vertex Lie algebra (conformal algebra) and vertex poisson algebra are revisited and certain general construction theorems of vertex poisson algebras are given. A notion of filtered vertex algebra is formulated in terms of a notion of good filtration and it i...
