Bar-Ilan Combinatorics Seminar (when) Sunday, 19 Tevet (Dec. 26), 14:00-15:30 (where) Room 201 (Math Department Seminar Room), Math and CS Building (216), Bar-Ilan University (who) Lev Shneerson (CUNY) (what) "On the growth functions of semigroups" Abstract: We study the asymptotic behavior of the growth functions in some classes of finitely generated and finitely presented semigroups and investigate conditions under which these semigroups have polynomial growth. In particular, we find new criteria for polynomial growth in finitely presented Rees quotients of free inverse semigroups. Most of the results of the talk are joint work with David Easdown (School of Mathematics and Statistics, The University of Sydney, Australia) ************************************************************************* You are all invited!
