DESCRIPTION:Speakers: Antonio Antunes (LPENS\, Paris)\n\nHigher-spin conse
 rved currents and charges feature prominently in integrable 2d QFTs in fla
 t space. Motivated by the question of integrable field theories in curved 
 space and by results of the conformal bootstrap\, we will consider the con
 sequences of higher-spin currents for QFTs in AdS2. Namely\, we will show 
 that their presence is much more constraining than in flat space in partic
 ular proving that it is impossible to preserve: (a) any higher-spin charge
 s when deforming a massive free field by interactions\, or (b) any spin-4 
 charges when deforming a CFT by a Virasoro primary. Along the way\, we wil
 l show that in AdS one cannot `partially' conserve a higher-spin current a
 nd explain how higher-spin charges lead to integer spacing in the spectrum
  of primaries\, and to constraints on correlation functions.\n\nhttps://in
