Math-Phys-Cat
Math-Phys-Cat is a Brazilian research group concerned with Mathematical-Physics, categorification and higher category theory and physics. We are mainly interested in mathematical aspects of classical and quantum field theories, especially those involving category theory and gauge theory, also in the axiomatization problem of astrophysics and in using category-theoretic language in order to unify and abstract concepts in classical algebra and in differential geometry.
