The technique of contractions and the known results in the study of cycles in 3-connected cubic graphs are applied to obtain the following result.Let G be a 3-c
Let Kn be a complete graph on n vertices.In this paper,we find the necessary conditions for the existence of a 6-cycle system of Kn L for every nearly 2-regular
Let ζ be a class of finite groups. A subgroup H of a finite group G is said to be ζs-quasinormal in G if there exists a normal subgroup T of G such that HT is
