DESCRIPTION:Title: <a href="https://researchseminars.org/talk/PHK-cohomolo
 gy-seminar/125/">Odd and generalized Wilson surfaces</a>\nby Olga Chekeres
  (University of l'Aquila\, Italy) as part of Prague-Hradec Kralove seminar
  Cohomology in algebra\, geometry\, physics and statistics\n\n\nAbstract\n
 In this talk I discuss various extensions and generalizations of Wilson su
 rface observables in gauge theories. Previously\, Wilson surface observabl
 es were interpreted as a class of Poisson sigma models. We profit from thi
 s construction to define and study the super version of Wilson surfaces. W
 e provide some 'proof of concept' examples to illustrate modifications res
 ulting from appearance of odd degrees of freedom in the target. We also ex
 plain some natural directions for defining the analogues of Wilson surface
  observables in higher dimensions.\n\nThe talk is mostly based on https://
 arxiv.org/abs/2403.09820. This is a joint work with Vladimir Salnikov.\n
