I will present how we found the hidden relativistic symmetry in the context of AdS2 and AdS3 integrable superstring theories (arXiv:1903.10759). Then I shall discuss how such symmetry can be used in AdS3 to write down the Thermodynamic Bethe Ansatz for massless non-relativistic modes from the one available in literature for massless relativistic modes.

It has been proposed that Vasiliev’s nonlinear equations can be extracted from a cubic action principle of the Chern–Simons type, built up from a set of differential forms, a trace operation and a star product inherited from the associative algebra, and a nilpotent differential containing the (gauged) de Rham differential. In this talk, we argue that all of these algebraic structures can be naturally modeled by a class of two-dimensional topological models, referred to as differential Poisson sigma models, which we analyse in some detail.
