Schur multipliers, spectral radius and Baum-Connes conjecture

Baum-Connes conjecture

Appears in collection : 2025 - T1 - WS2 - Tempered representations and K-theory

We will discuss Schur multipliers, strong property (T) and the difficulty of proving open cases of the Baum-Connes conjecture with known methods. I will recall basic facts on Schur multipliers, and then my own work, and an article of Benben Liao.
