內(nèi)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.
