The COST Action

The aim of the COST Action "Fundamental Challenges in Theoretical
Physics" is to develop a comprehensive approach for studying
strongly-interacting systems in classical and quantum physics. The
Action brings together theoretical and mathematical physicists with
expertise in quantum field theory, string theory, gravity, geometry and
information theory, establishing the first network of this kind centred
around Europe. You can join the action by clicking here.
