0 On the restricted matching of graphs in surfaces ∗
A connected graph G with at least 2m + 2n + 2 vertices is said to have property E(m,n) if, for any two disjoint matchings M and N of size m and n respectively, G has a perfect matching F such that M ⊆ F and N ∩ F = ∅. In particular, a graph with E(m, 0) is m-extendable. Let μ(Σ) be the smallest integer k such that no graphs embedded on a surface Σ are k-extendable. Aldred and Plummer have prove...
متن کاملOn the restricted matching extension of graphs on the torus and the Klein bottle
Aldred and Plummer proved that every 6-connected even graph minimally embedded on the torus or the Klein bottle is E(1, n)(n ≤ 3) and E(0, n)(n ≤ 5) [R.E.L. Aldred, M.D. Plummer, Restricted matching in graphs of small genus, Discrete Math. 308 (2008) 5907–5921]. In this paper, we can remove the upper bounds on n by showing that every even 6-regular graph G embedded on the torus or the Klein bot...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
