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.
