New Perspectives on
Theoretical Physics: Representation Theory.
ABSTRACT: In this talk I will describe the relationship between
theoretical physics and representation theory (RT). I will
introduce many physical concepts (with examples), such as BPS
spectra, S-duality, 't Hooft line operators and groups, and relate
them to theorems and concepts of RT (such as categories of modules
over path algebras, mutation invariance of the derived categoriy
of quiver representations, Ginzburg algebras, cluster categories
and more).
The main reference for the first part of the talk is [1] .
Afterwards, I will focus on some new results -- current work with
S. Cecotti -- on how to exploit RT to give a full classification
of a class of holomorphic integrable systems (a.k.a.
Supersymmetric Quantum Field Theories). For partial results, refer
to [2].
