Actions of higher rank groups on uniformly convex Banach spaces
Tim de Laat, Mikael de la Salle
We prove that all isometric actions of higher rank simple Lie groups and their lattices on arbitrary uniformly convex Banach spaces have a fixed point. This vastly generalises a re…

A complete characterization of connected Lie groups with the Approximation Property
Uffe Haagerup, Søren Knudby, Tim de Laat
We give a complete characterization of connected Lie groups with the Approximation Property for groups (AP). To this end, we introduce a strengthening of property (T), that we call…

Strong property (T) for higher rank simple Lie groups
Tim de Laat, Mikael de la Salle
We prove that connected higher rank simple Lie groups have Lafforgue's strong property (T) with respect to a certain class of Banach spaces containing many class…
