DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TQFT/100/">T
 he super period map and the projectedness of supermoduli space</a>\nby Nad
 ia Ott (University of Southern Denmark) as part of Topological Quantum Fie
 ld Theory Club (IST\, Lisbon)\n\n\nAbstract\nIn 2014\, Donagi and Witten p
 roved that supermoduli spaces $\\mathfrak{M}_g$ of genus $g$ super Riemann
  surfaces are not projected for genus $g \\geq 5$. In joint work with Ron 
 Donagi\, we show that $\\mathfrak{M}_g$ is projected\, for all genus $g$\,
  away from the so-called bad divisor. In other words\, we show that the co
 mplement $U_g$ of $\\mathcal{B} \\subset \\mathfrak{M}_g$ is a projected o
 pen subscheme of $\\mathfrak{M}_g$. Furthermore\, at least in genus $g = 2
 $ and $g = 3$\, we show that the super period map defines a projection $U_
 g \\to U_{g\,\\mathrm{bos}}$.\n
