Automaton groups and square complexes (Ievgen Bondarenko, University of Kyiv)

21.03.2017 10:30

Any automaton-transducer with the same input and output alphabets gives rise to a square complex: one can take a unit square with labeled and oriented edges for each arrow in automaton and glue these squares to get a complex. In this talk, based on a joint work with Bohdan Kivva, I will discuss the connection between groups generated by automata, tiling properties of associated collection of squares, and residual properties of the fundamental groups of these square complexes.
