Abstract

Mathematics Mathematics, Applied Physical Sciences Science & Technology
We construct orthogonal double covers of K-n,K-n by Pm+1 U* Sn-m where n and m are integers, 2 <= m <= 10, m <= n and Pm+1 U* Sn-m is a tree obtained from the path Pm+1 with m edges and a star Sn-m with n-m edges by identifying an end-vertex of Pm+1 with the center of Sn-m.
