内容記述 | In this paper, we study the edge flip operations on some classes of clique-acyclic digraphs (that is, digraphs containing no directed triangle), especially we show that if $G$ is a simple undirected graph whose every induced subgraph has a vertex $v$ whose degree $5(v)¥leqq 7$, any two clique-acyclic orientations $¥pi$ and $¥pi^{¥prime}$ have a sequence of clique-acyclic orientations $¥pi=¥pi 0,$ $¥pi_{1},$ $¥ldots$ , $¥pi¥iota=¥pi^{¥prime}$ such that we obtain $¥pi$, by reversing the orientation of one single edge of $¥pi_{i-1}$ , (then we call that $¥pi$' is attainable from $¥pi$). The latter bound "$¥delta(G)¥leqq 7$'' is sharp. Actually, if $G$ is a connected 8-regular graph, then there are exactly five examples of $G$ each of which has a clique-acyclic orientation such that, if we flip any edge of it, the resulting new orientation has a directed triangle. Last, we show that, except for the above five examples of $G$ , any two clique-acyclic orientations of a connected graph $G$ whose maximum degree $¥Delta(G)¥leqq 8$ , are attainable from one to another. | |||||
