报告题目:On Graph Isomorphism Problem
报告摘要: Let $G$ and $H$ be two simple graphs. A bijection $\\phi:V(G)\ightarrow V(H)$ is called an {\\it isomorphism} between $G$ and $H$ if $(\\phi\\hspace{0.5mm} v_i)(\\phi\\hspace{0.5mm} v_j)\\in E(H)$ $\\Leftrightarrow$ $v_i v_j\\in E(G)$ for any two vertices $v_i$ and $v_j$ of $G$. As well-known, the problem of determining whether or not two given graphs are isomorphic is called {\\it Graph Isomorphism Problem}. In this talk we shall present some new approaches developed for GI and a deterministic algorithm solving Graph Isomorphism Problem in time $n^{ O( \\log n ) }$.
