In the past few years, there has been several exciting developments at the confluence of pure mathematics and theoretical computer science. These include:

The refutations of Connes’ embedding problem and the Aldous–Lyons conjecture using tools from group stability, complexity theory and quantum information theory.
The construction of good locally testable codes and good quantum LDPC codes, using breakthroughs in high dimensional expansion.
This conference is devoted to these results and the theory surrounding them, and will celebrate the 70’s birthday of Alex Lubotzky, whose contributions range from establishing the very foundations of these fields, to the most recent breakthroughs.
