SUMMARY:Ben Hoare (ETH Zurich) - Deformations of AdS superstrings and Weyl 
 symmetry
DESCRIPTION:Deformations of AdS superstrings and Weyl symmetry\nIn this tal
 k I will discuss recent developments in understanding the Weyl invariance 
 (or lack thereof) of integrable deformations of AdS superstrings. One well
 -known example of such a deformation is the TsT transformation\, which inv
 olves a T-duality\, a shift introducing the deformation parameter\, and a 
 reverse T-duality. After introducing the deformed model\, I will present t
 wo alternative constructions: (i) as a non-abelian duality\, and (ii) as a
  homogeneous Yang-Baxter deformation. In the second part of the talk I wil
 l outline how this extends to a general relationship between non-abelian d
 uality and homogeneous Yang-Baxter deformations\, and discuss the conseque
 nces for the Weyl invariance of the deformed models. Depending on time I w
 ill also touch on the extent to which these results can be extended to the
  inhomogeneous Yang-Baxter deformation\, a.k.a. the eta or q deformation.
