Neighborhood Unions for the Existence of Disjoint Chorded Cycles in Graphs

A chorded cycle is a cycle with at least one chord. We prove that if G is a simple graph with order n  ≥ 4 k and for each nonadjacent pair of vertices x and y , then G contains k vertex-disjoint chorded cycles. The degree condition is sharp in general.
