Algebraic Complexity Theory is a vibrant field that has been seeing a tremendous amount of activity in the recent years. Its classical questions have been interwoven with deep questions from algebraic geometry, invariant theory, and representation theory, with recent exciting connections to metacomplexity and proof complexity. The workshop brings together experts from these fields to discuss the current state of the art, discover new connections, and set the directions for the future. Each plenary speaker will explain a recent result and break down its main ideas to a level that is accessible for the mathematically diverse audience. Remote participation via MS Teams is possible.
