OGGW02 - Actions on graphs and metric spaces

This talk deals with algorithms for linear groups over infinite fields. A principal motivation of this research is applications of linear groups in many areas of mathematics including geometry. Exploiting Zariski density and the strong approximation property, we have developed new methods for practical computation with finitely generated linear groups. In the talk we present algorithms to investigate properties and structure of linear groups based on these methods. We then demonstrate how the algorithms have been applied in the solution of problems via computer-aided experimentation. Joint work with Dane Flannery and Alexander Hulpke.
