DEKOMPOSISI GRAF HELM

Abstract

Abstract: Decomposition of graph G is a collection of {Hi} from sub graph G until Hi = 〈Ei〉 for Ei subset E (G) and {Ei} is partitions of E (G). If {Hi} is a decomposition of G, it can be written as the addition of the sides and G is decomposed into sub graphs where n = |{Hi}|. In other words, is the decomposition of graph G. Helm Hn graph with n ≥ 3 and n is even number which can be partitioned into sub graph   which is in the form of 2K₂, where Hn = So, helmet Hn graph with n ≥ 3 and n is an even number of 2K₂-decomposition. The Hn helm graph with n > 3 can be partitioned into sub graph Ai = 〈Ei〉 which is in the form of 3K₂, where . So that the Hn helm graph with n > 3 is 3K₂-decomposition.
