SUMMARY:Tim Meier (U. Santiago de Compostela) - 
DESCRIPTION:Speaker: Tim Meier\n\nTitle: Noncommutative deformations of gau
 ge theories via Drinfel’d twists of the scale symmetry\n\nAbstract: Inte
 grability within the AdS/CFT correspondence provides a powerful framework 
 for studying quantum field theories and their AdS duals at finite coupling
 \, offering an ideal playground for testing the duality and exploring nonp
 erturbative aspects of QFT. In recent years\, considerable attention has b
 een focused on integrable deformations of the AdS5 string\, particularly t
 he class of homogeneous Yang–Baxter deformations\, whose CFT duals are c
 onjectured to be twisted versions of N=4 SYM. When these deformations act 
 on the AdS sector of the background\, they generically give rise to noncom
 mutative field theories. However\, a key challenge has been the lack of a 
 systematic construction of gauge-invariant noncommutative Yang–Mills the
 ories for the relevant twists.\nIn this talk\, I will present a new approa
 ch that resolves this issue by providing a gauge-invariant formulation of 
 noncommutative Yang–Mills theory for twists generated by scale and Poinc
 aré transformations. This framework opens the door to investigating the C
 FT duals of a broad class of Yang–Baxter–deformed AdS backgrounds and 
 paves the way for deeper tests of integrability-based deformations within 
 AdS/CFT.
