Information

Ziele, Inhalte und Methode der Lehrveranstaltung

This course is focused on certain applications of category theory in mathematical physics. We will study an approach to observable algebras in the Batalin-Vilkovisky formalism for gauge theories via factorisation algebras. Factorisation algebras are certain cosheaves on topological spaces which are apt to model observable algebras in euclidean signature. Along the way, we will introduce the necessary notions from homological algebra as well as the functor-of-points perspective from algebraic geometry in order to motivate the reformulation of perturbative field theory as the study of formal moduli problems. Some essential examples such as scalar field theory, Yang-Mills theory, and Chern-Simons theory will be treated in this context. This will lead up to a discussion of some open problems in the area.

Prerequisites: Familiarity with basic algebra, basic point-set topology, basic category theory, and basic manifold theory. Familiarity with gauge theories is advantageous but not necessary. We will recall the necessary material depending on need.

The course is aimed at physicists and mathematicians in equal measure.

Art der Leistungskontrolle und erlaubte Hilfsmittel

We will discuss exercises together in class. Participation in these discussions is integral to the course; submission of solutions is otherwise not necessary.

Evaluation will be based on one short written midterm test in late November and one oral test at the end of the term.

Mindestanforderungen und Beurteilungsmaßstab

In order to pass the course, students must pass both tests by obtaining at least 40% of the total points in each test. The grade in the midterm test will contribute 40% and the grade in the oral test will contribute 60% to the final grade.
