# On simple groups acting on trees

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.

# GAGTA8

## Monday, 21st Jul 2014

[Newcastle, NSW]

The eighth edition of the conference series GAGTA (Geometric and Asymptotic Group Theory with Applications) will be held in Newcastle, Australia July 21-25 (Mon-Fri) 2014.

GAGTA conferences are devoted to the study of a variety of areas in geometric and combinatorial group theory, including asymptotic and probabilistic methods, as well as algorithmic and computational topics involving groups. In particular, areas of interest include group actions, isoperimetric functions, growth, asymptotic invariants, random walks, algebraic geometry over groups, algorithmic problems and their complexity, generic properties and generic complexity, and applications to non-commutative cryptography.

# EViMS 2: Effective use of Visualisation in the Mathematical Sciences

## Friday, 21st Nov 2014

[Australian National University]

The Mathematical Sciences Institute will host a three day workshop on more effective use of visualization in mathematics, physics, and statistics, from the perspectives of education, research and outreach. This is the second EViMS meeting, following the highly successful one held in Newcastle in November 2012. Our aim for the workshop is to help mathematical scientists understand the opportunities, risks and benefits of visualization, in research and education, in a world where visual content and new methods are becoming ubiquitous.
