- Аннотация: This talk is devoted a construction of finitely presented semigroups with some exotic properties. The main result is as follows. Theorem There exists a constant M such that if \alpha > M is a recursive real number (i.e. there is an algorithm for calculating each digit of its decimal presentation) then there exists a semigroup G such that GK(G)=\alpha. The proof is based on a technique of Minsky machines (which was learned by one author from conversations with Mark Sapir).
