The 4-girth-thickness of the complete multipartite graph

SUMMARY

The g-girth-thickness ?(g, G) of a graph G is the smallest number of planar subgraphs of girth at least g whose union is G. In this paper, we calculate the 4-girth-thickness ?(4, G) of the complete m-partite graph G when each part has an even number of vertices.

Burger and Vuuren defined the size multipartite Ramsey number for a pair of complete, balanced, multipartite graphs mj(Kaxb,Kcxd), for natural numbers a,b,c,d and j, where a,c >= 2, in 2004. They have also determined the necessary and sufficient condi... see more

Let HH be a directed acyclic graph (dag) that is not a rooted star. It is known that there are constants c=c(H)c=c(H) and C=C(H)C=C(H) such that the following holds for DnD_n, the complete directed graph on nn vertices. There is a set of at most ClognC\l... see more

A well-known conjecture of Richard Stanley posits that the hh-vector of the independence complex of a matroid is a pure O{\mathcal O}-sequence. The conjecture has been established for various classes but is open for graphic matroids. A biconed graph is a... see more

We prove that the necessary divisibility conditions are sufficient for the existence of resolvable group divisible designs with a fixed number of sufficiently large groups. Our method combines an application of the Rees product construction with a stream... see more
