DESCRIPTION:Title: <a href="https://researchseminars.org/talk/EQuAL/17/">Q
 uantum Transformation Groupoids</a>\nby Frank Taipe (Université Paris-Sac
 lay) as part of European Quantum Algebra Lectures (EQuAL)\n\n\nAbstract\nW
 e define quantum transformation groupoids\, a class of multiplier Hopf alg
 ebroids generalizing transformation groupoids and algebraic quantum groups
 . An interesting characteristic of this algebraic class is that it admits 
 a Pontryagin-like duality. In the first part of the talk\, we will discuss
  how the study of quantum transformation groupoids appears in a Galois-typ
 e theory of inclusions of von Neumann algebras. Then in the second part\, 
 we will give the construction of a quantum transformation groupoid from a 
 braided commutative measured Yetter-Drinfeld *-algebra on an algebraic qua
 ntum group in the sense of A. Van Daele.\n
