Moreover, the inner automorphism group of a basic quasi-hereditary algebra acts transitively on the set of its exact Borel subalgebras.

【摘要】： 正 It is proved that the exact Borel subalgebras of a basic quasi-hereditary algebra are conjugate to each other.

All graphs are finite simple undirected graph with no isolated vertices in this paper. It is completed the classification of graphs on which a semidihedral group acts edge-transitively.
