Abstrakt: We prove the following 30 year-old conjecture of Győri and Tuza: the edges of every n-vertex graph G can be decomposed into complete graphs C1, . . . , C of orders two and three such that |C1|+ · · · +|C| ≤ (1/2+ o (1)) n2. This result implies the asymptotic version of the old result of Erdős, Goodman and Pósa that asserts the existence of such a decomposition with ℓ ≤ n2/4. [ABSTRACT FROM AUTHOR]
