Higher categorical structures in quantum field theory
Project description
Higher category theory plays an increasingly important role in the mathematical formulation of quantum field theory (QFT). It provides powerful tools to investigate and understand subtle aspects associated with gauge symmetries and thereby opens up new avenues towards designing refined axiomatic frameworks for QFT that are capable to describe quantum gauge theories such as Yang-Mills theory.
This is an interdisciplinary PhD project in the intersection of mathematical physics, algebra and topology. The project could focus either on new developments in higher categorical algebraic QFT, or on the construction of new examples in this framework.
