해외 바카라题目二：Removable edges 해외 바카라 bricks

报 告 人：王艳 教授

해외 바카라摘要：A connected nontrivial graph G is matching covered}, if every edge 해외 바카라 G is contained in a perfect matching 해외 바카라 G. An edge e 해외 바카라 a matching covered graph G is removable if G-e is still matching covered. Lovasz and Plummer introduced removable edges in connection with ear decompositions 해외 바카라 matching covered graphs. A matching covered graph G is a brick if and only if G is 3‐connected and for any two distinct vertices u and v 해외 바카라 G, G−u−v has a perfect matching. The existence 해외 바카라 removable edges, especially 해외 바카라 special types, plays an important role in the generation 해외 바카라 some bricks. In this talk, we introduce the related background and our results on removable edges in bricks.

해외 바카라题目三：Splitting fields and algebraic degrees 해외 바카라 Cayley graphs

报 告 人：鲁卢 副教授

해외 바카라摘要：In this talk, we introduce the concept 해외 바카라 splitting fields and algebraic degrees 해외 바카라 graphs. Firstly, we completely determine the splitting fields 해외 바카라 undirected  Cayley graphs over abelian groups. Next, we give a characterization 해외 바카라 the splitting fields 해외 바카라 undirected  Cayley graphs over dihedral groups. At last, we completely determine the splitting fields 해외 바카라 mixed graphs over abelian groups.
