Prospective students

Research

We provide Bachelor, Master, and Doctoral theses topics at the interface between mathematics and physics. Possible research topics include, but are not limited to, constructive quantum field theories, conformal field theory, random geometry, supersymmetric gauge theories and fractals. If you are interested in one of our research topics, please feel free to contact Kalle Kytölä, Eveliina Peltola, or Oscar Kivinen.

We also provide Summer Internships for outstanding students. These are advertised in the department's website.

Teaching

You are also welcome to take part in any of our lecture courses related to mathematical physics.

11.11. 10:15 Shinji Koshida (Aalto University): Tensor categories of Virasoro modules – M3 (M234)
This talk is meant as a complement to Alexiss talk from last week. The goal is to demystify the construction of tensor categories of modules for vertex operator algebras (VOAs). There is a famously large body of work on this by HuangLepowsky and HuangLepowskyZhang, and it is certainly reasonable for most people to treat it as a "black box". However, I will try to explain that the tensor product of VOA modules is not as mysterious as it might seem. In fact, it fits into quite familiar mathematical ideasarising from a universal property, just as so many other constructions do. To keep things concrete, I will focus on the Virasoro algebra, following Alexis. So no prior knowledge of VOA theory will be needed.
