We give a simple proof of the fact (which follows from the Robertson Seymour theory) that a graph which is minimal of genus g cannot contain a subdivision of a large grid. Combining this with the tree-width theorem and the quasi-wellordering of graphs of bounded tree-width in the Robertson Seymour t

## Abstract For a simple graph of maximum degree ฮ”, it is always possible to color the edges with ฮ” + 1 colors (Vizing); furthermore, if the set of vertices of maximum degree is independent, ฮ” colors suffice (Fournier). In this article, we give a short constructive proof of an extension of these re
