DESCRIPTION:Title: <a href="https://researchseminars.org/talk/EGSS/21/">Th
 e generalized geometry of backgrounds with gaugino condensates</a>\nby Mar
 iana Graña (IPhT Saclay) as part of Exceptional geometry seminar series\n
 \n\nAbstract\nMotivated by their potential to stabilise moduli\, we inspec
 t  type II backgrounds with gaugino condensates on D-branes. We use the la
 nguage of generalized complex geometry which is the most adapted to accoun
 t for their back-reaction. After reviewing the effective 4d physics reveal
 ed by Kachru\, Kallosh\, Linde and Trivedi\, as well as the basic concepts
  of generalized complex geometry\,  I will show in this talk how the gaugi
 no condensates modify the action and the supersymmetry conditions\, concen
 trating on compactifications to four dimensions\, and discuss some of its 
 salient features. We will show how the equations reproduce the phenomenon 
 of moduli stabilisation\, and comment on a local solution that matches the
  on-shell value obtained from the four-dimensional effective action.\n
