Group Meeting: Review of Higher Spin Theories - Part 3
2019-12-09This will be the concluding part of the series of lectures on Higher Spin theories by Mirian Tsulaia.
Abstract: In today's talk we will discuss Vasiliev's formulation of Higher Spin theories, focussing in particular on the topic of free and nonlinear unfolded equations.

Speaker: Seva Nikulin.
Title: "De Sitter space as a space of probability distributions".
Journal club seminar: Knots, the Jones Polynomial, and Khovanov homology
2019-12-04Speaker: Andrew Lobb
Title: Knots, the Jones Polynomial, and Khovanov homology.
Abstract : I shall give constructions of the Jones polynomial and of Khovanov homology. These are both invariants of knots -- the former is a polynomial, the latter is a vector space. They are interesting for many reasons and their construction is beautiful. There are deep connections with physics on which I'm not really qualified to comment (apologies), but those able may try looking at Kauffman's book "Knots and Physics", Witten's "Quantum Field Theory and the Jones Polynomial", or Gukov-Schwarz-Vafa's "Khovanov-Rozansky homology and topological strings". No knowledge of anything is assumed, and questions are encouraged.
[Seminar] "Making string theory great again" by Prof. Eoin Ó Colgáin
2019-12-02Speaker: Prof. Eoin Ó Colgáin from APCTP
Journal club seminar: Basics of Covariant Quantization of Superstring
2019-11-27Mirian Tsulaila will tell us about "Basics of Covariant Quantization of Superstring". The useful references are ICTP Lectures on Covariant Quantization of the Superstring and Multiloop Amplitudes and Vanishing Theorems using the Pure Spinor Formalism for the Superstrin The Green-Schwarz formulation of superstring is described in the String theory book by M. Green, J. Schwarz and E. Witten (chapter 5).
Group Meeting: Review of Higher Spin Theories - Part 2
2019-11-25In this talk Mirian Tsulaia will continue with his review of Higher Spin Theories.
Abstract: This a continuation of the previous talk in this series. Today we shall discuss Vasiliev's formalism and in particular talk about free unfolded equations.
