Homotopy minimal periods for expanding maps on infra-nilmanifolds
We prove that the sets of homotopy minimal periods for expanding maps on n -dimensional infra-nilmanifolds are uniformly cofinite,i.e., there exists a positive integer m 0 , which depends only on n , such that for any integer m ≥ m 0 , for any n -dimensional infra-nilmanifold M , …
