Abstract:
Using the fermionic basis we conjecture explicit formulae
for the one-point functions in the sinh-Gordon model on a cylinder at finite temperature). The conjecture is checked against known results.

Higher-spin symmetry in AdS and CFT
Eugene Skvortsov
(AEI Potsdam)
Abstract:
I will discuss the implications of extended symmetries in higher dimensional CFT's and show that the algebra they generate, the higher-spin algebra, is unique (which extends Maldacena-Zhiboedov results). As an infinite-dimensional extension of conformal symmetries higher-spin algebras can be used to restrict correlation functions and I will present an explicit formula that computes all correlators in unbroken Vasiliev higher-spin theory.

Integrable q-deformation of the AdS5 x S5 superstring
Marc Magro
(ENS Lyon)
Abstract:
I will first review the algebraic structure related to the classical integrability of sigma models at the hamiltonian level. I will then show how this hamiltonian perspective enables to construct an integrable q-deformation of the AdS5 x S5 superstring action.
