Stability, Non-approximate Groups and High Dimensional Expanders by Alex Lubotzky

Explore a 50-minute conference talk on stability, non-approximate groups, and high dimensional expanders presented by Alex Lubotzky at the International Centre for Theoretical Sciences. Delve into topics such as residually finite and sophic groups, non-approximate groups, and stability criterion for nonuniform lattices. Learn about recent breakthroughs in the field and gain insights into the proof of stability.
