We prove that the vertex set of a simple graph with minimum degree at least s + t -1 and girth at least 5 can be decomposed into two parts, which induce subgraphs with minimum degree at least s and t, respectively, where s, t are positive integers โฅ 2.

โฆ Synopsis
The generating function for labelled graphs in which each vertex has degree at least three is obtained by the Principle of Inclusion and Exclusion. Asymptotic and explicit values for the coefficients are calculated in the connected case. The results are extended to bipartite graphs.

This note presents a solution to the following problem posed by Chen, Schelp, and Soltรฉs: find a simple graph with the least number of vertices for which only the degrees of the vertices that appear an odd number of times are given.
Let T = (V, E) be a tree with a properly 2-colored vertex set. A bipartite labeling of T is a bijection ฯ: V โ {1, . . . , |V |} for which there exists a k such that whenever ฯ(u) โค k < ฯ(v), then u and v have different colors. The ฮฑ-size ฮฑ(T ) of the tree T is the maximum number of elements in the
In this article, we show that all quadrangulations of the sphere with minimum degree at least 3 can be constructed from the pseudo-double wheels, preserving the minimum degree at least 3, by a sequence of two kinds of transformations called "vertex-splitting" and "4-cycle addition." We also consider
