 ZERODIMENSIONAL SYMMETRY SEMINAR
 Speaker: Dr Stephan Tornier, The University of Newcastle
 Title: An introduction to selfsimilar groups
 Location: Room MC102, McMullin (Callaghan Campus) The University of Newcastle
 Time and Date: 2:00 pm, Mon, 3^{rd} Sep 2018
 Abstract:
We introduce the notion of selfsimilarity for groups acting on regular rooted trees as well as their description using automata and wreath iteration. Following the definition of Grigorchuk's group we show that it is an infinite, finitely generated 2group. The proof illustrates the use of selfsimilarity.

 Title: On locallytransitive discrete automorphism groups of biregular trees
 Abstract for On locallytransitive discrete automorphism groups of biregular trees:
I'll give an overview of some recent developments in the theory of groups of automorphisms of trees which are discrete in the full automorphism group of the tree and are locallytransitive. I'll also mention some questions which have been provoked by this work.
 Speaker: Dr Stephan Tornier, The University of Newcastle
 Title: On a generalization of BurgerMozes universal groups
 Abstract for On a generalization of BurgerMozes universal groups:
We generalize the BurgerMozes universal groups acting on regular trees by prescribing the local action on balls of a given radius, and study the basic properties of this construction. We then apply our results to prove a weak version of the GoldschmidtSims conjecture for certain classes of primitive permutation groups.
