Four-regular graphs that quadrangulate both the torus and the Klein bottle
In this paper, we characterize 4-regular graphs which can quadrangulate both the torus and the Klein bottle.
متن کاملMatching extension in quadrangulations of the torus
A graph G is said to have the property E(m,n) if, given any two disjoint matchings M and N where |M | = m and |N | = n respectively and M ∩ N = ∅, there is a perfect matching F in G such that M ⊆ F and F ∩N = ∅. This property has been previously studied for triangulations of the plane, projective plane, torus and Klein bottle. Here this study is extended to quadrangulations of the torus.
متن کاملQueens graphs for chessboards on the torus
Ve consider the independence, domination and independent domination numbers of graphs obtained from the moves of queens on chessboards drawn on the torus, and determine exact values for each of these parameters in infinitely many cases.
متن کاملRigidity of pseudo-free group actions on contractible manifolds
In this article, we announce joint work with Frank Connolly and Jim Davis [6]. This follows an earlier case study of pseudo-free involutions on the n-torus carried out in [5]. The author is grateful to the organizers of the RIMS conferences where these results were disseminated in Asia: Transformation Groups and Surgery Theory (Masayuki Yamasaki, August 2010), Transformation Groups and Combinat...
