A density Corr\'adi-Hajnal Theorem

Combinatorics 2017-07-31 v2

Abstract

We find, for all sufficiently large nn and each kk, the maximum number of edges in an nn-vertex graph which does not contain k+1k+1 vertex-disjoint triangles. This extends a result of Moon [Canad. J. Math. 20 (1968), 96-102] which is in turn an extension of Mantel's Theorem. Our result can also be viewed as a density version of the Corradi-Hajnal Theorem.
