Exponential and intermediate growth of some free algebraic objects

초록본문(Abstract) I will discuss some recent work on counting the growth (in the sense of Milnor and Schwarz) of certain free objects. These free objects – free inverse semigroups, and free regular *-semigroups, respectively – lie somewhere between semigroups and groups, and have a wealth of combinatorial tools and tricks available to them, including word rewriting systems. This is in part joint work with M. Kambites, N. Szakács, R. Webb (all in Manchester).
