Geometric and Asymptotic Group Theory (GAGTA)

 In Workshop reports

Newcastle, Australia, 21–25 July 2015

This meeting explored a wide range of areas within geometric and combinatorial group theory, spanning asymptotic and probabilistic methods, as well as algorithmic and computational topics involving groups. Areas of interest included group actions, isoperimetric functions, growth, asymptotic invariants, random walks, algebraic geometry over groups, the complexity of algorithmic problems, generic properties and complexity, and applications to noncommutative cryptography.

Featured presentations were the event opener by Professor Sarah Rees on recent advances in surveying sofic groups, and the closing address by Associate Professor Kate Juschenko exploring cutting-edge amenability research. The University of Newcastle Vice Chancellor and President, Professor Caroline McMillen’s address during the conference banquet was also a highlight.

Professor Eamonn O’Brien gave an excellent talk illustrating links between his work on highly practical, computational (finite) group theory to infinite, geometric and asymptotic group theory.

With excellent schedule pace, high quality research presentations and opportunity for informal discussion, the event was a great success.
