Abstract

In this paper, we give a relationship among the period, the minimal supporting genus vg (L) of a periodic virtual link L that admits a minimal supporting genus periodic diagram, and vg (L*) of its factor link L*. As an application, it is shown that if L is a non-classical virtual link of period n which admits a minimal supporting genus n-periodic diagram, then n ≤ 2 vg (L) + 1, except a certain class of periodic virtual links.
