DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TQFT/93/">Pu
 re spinor techniques in (twisted) supergravity</a>\nby Fabian Hahner (Heid
 elberg University) as part of Topological Quantum Field Theory Club (IST\,
  Lisbon)\n\n\nAbstract\nThe pure spinor superfield formalism gives a syste
 matic and geometric technique to construct supersymmetric field theories f
 rom algebro-geometric input data. Crucially\, this procedure provides supe
 rfield descriptions where the actions of the supersymmetries are strict an
 d ompatible with twisting. In this talk\, I will demonstrate the merits of
  the formalism using the example of eleven-dimensional supergravity. In pa
 rticular\, I present a uniform construction of the interacting theory and 
 all its twists realizing them as generalizations of Poisson–Chern–Simo
 ns theory. In addition to simplifying the computation of twists immensely\
 , this also sheds some new light on the supergeometric origin of the super
 gravity theory. The talk is based on joint work with Ingmar Saberi.\n
