Summary
Takahasi’s Theorem on chains of subgroups of bounded rank in a free group is generalized to severalclasses of semigroups. As an application, it is proved that the subsemigroups of periodic points are finitelygenerated and periodic orbits are bounded for arbitrary endomorphisms for various semigroups. Some ofthese results feature classes such as completely simple semigroups, Clifford semigroups or monoids definedby balanced one-relator presentations.
