• Speaker: Mr Chris Banks, CARMA, The University of Newcastle
  • Title: On simple groups acting on trees
  • Location: Room V205, Mathematics Building (Callaghan Campus) The University of Newcastle
  • Time and Date: 4:00 pm, Wed, 23rd Apr 2014
  • Abstract:

    In this talk I will present a general method of finding simple groups acting on trees. This process, beginning with any group $G$ acting on a tree, produces more groups known as the $k$-closures of $G$. I will use several examples to highlight the versatility of this method, and I will discuss the properties of the $k$-closures that allow us to find abstractly simple groups.
