DESCRIPTION:[b]Seminar by Ingmar Saberi [/b](University of Munich) [nl]\n[
 b]Abstract:[/b][nl]\nIn recent years\, there has been a great deal of pro
 gress on ideas related to twisted supergravity\, building on the definiti
 on given by Costello and Li. Much of what is explicitly known about these
  theories comes from the topological B- model\, whose string field theory
  conjecturally produces the holomorphic twist of type IIB supergravity. P
 rogress on eleven-dimensional supergravity has been hindered\, in part\, 
 by the lack of such a worldsheet approach. I will discuss a rigorous comp
 utation of the twist of the free eleven-dimensional supergravity multiple
 t\, as well as an interacting BV theory with this field content that pass
 es a large number of consistency checks. Surprisingly\, the resulting hol
 omorphic theory on flat space is closely related to the infinite-dimensio
 nal exceptional simple Lie superalgebra E(5|10)\, and another such except
 ional simple algebra - E(3|6) - appears in the context of M5-branes. This
  is joint work with Surya Raghavendran and Brian Williams.[nl]\n[nl]
