Bieberbach groups and C*-rigidity

Stuart White (University of Glasgow)

Wednesday 13th January, 2016 16:00-17:00 Maths 522


There are many ways to construct a ring or algebra from a group, including entirely algebraic constructions and suitable analytic completions of these. Rigidity asks to what extent such processes remember the initial group.  I'll give a general survey, not assuming any prior familiarity with the more analytic objects.  Any new results I get to will be joint work with Søren Kundby, Sven Raum and Hannes Thiel.
