Orbit problems for free-abelian times free groups and related families
André Carvalho, Jordi Delgado
We prove that the Brinkmann Problems (BrP & BrCP) and the twisted-conjugacy Problem (TCP) are decidable for any endomorphism of a free-abelian times free (FATF) group Fn x Z^m. Fur…

Decidability of the Brinkmann Problems for endomorphisms of the free group
André Carvalho, Jordi Delgado
We show that both the Brinkmann Problem (BrP) and the Brinkmann Conjugacy Problem (BrCP) are decidable for endomorphisms of the free group Fn.
