内容摘要:
The study of arc-pancyclicity of tournaments has a long history. Alspach proved that every arc of a regular tournament is in a -cycle for each .
In this talk, we extend the arc-pancyclicity for regular tournaments to multipartite tournaments. we prove that every arc of a regular -partite tournament with belongs to cycles of pairwise distinct lengths. Moreover, we also proved that for any two partite sets of with ,, there is a -path that transverses exactly partite sets for each . These results extends Alspach's theorem for regular tournaments to regular multipartite tournaments.
