DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LAGOON/109/"
 >TFTs via DAG</a>\nby Tristan Bozec (Université Angers\, France) as part 
 of Longitudinal Algebra and Geometry Open ONline Seminar (LAGOON)\n\n\nAbs
 tract\nOne very nice feature of derived algebraic geometry\, and specifica
 lly shifted symplectic geometry\, is how convenient it is to tackle topolo
 gical field theories. We will first review the recent history of this appr
 oach\, through the fundamental use of mapping stacks and the Betti shape. 
 We will illustrate our review with many very concrete examples and noncomm
 utative applications\, before explaining how the (recently proved) Moore--
 Tachikawa conjecture lead us to considering the Dolbeault shape in view of
  defining a new TFT associated to Higgs fields. This reports an ongoing co
 llaboration with Damien Calaque\, Julien Grivaux and Hugo Pourcelot.\n\nTh
