Abstract:

This talk will be a survey on hardness amplification, its use in derandomization, and connections to coding theory. However, I will endeavor to motivate and discuss the results in the above work in progress.

We use recent constructions of high-dimensional expanders to improve the rate of  locally approximately list-decodable codes and the input size in hardness amplification for both uniform and non-uniform models.

Joint work with Yotam Dikstein, Max Hopkins and Toniann Pitassi
