A chordless cycle in a graph, also called a hole or an induced cycle, is a cycle such that no two vertices of the cycle are connected by an edge that does not itself belong to the cycle. An antihole is the complement of a graph hole. Chordless cycles may be used to characterize perfect graphs: by the strong perfect graph theorem, a graph is perfect if and only if none of its holes or anti… Web4. First suppose for contradiction that the length of the longest cycle C is 2 k − 1. Then consider the set of vertices in C, which are connected with vertices outside C. It has cardinality at least k. Otherwise, by deleting these vertices, the graph left is still connected. Then by pigeonhole principle there are two adjacent verticies A and ...
