DESCRIPTION:Title: <a href="https://researchseminars.org/talk/EGSS/19/">Ex
 otic Branes from del Pezzo Surfaces [UNUSUAL TIME]</a>\nby Justin Kaidi as
  part of Exceptional geometry seminar series\n\n\nAbstract\nWe revisit a c
 orrespondence between toroidal compactifications of M-theory and del Pezzo
  surfaces\, in which rational curves on the del Pezzo are related to 1/2-B
 PS branes of the corresponding compactification. We argue that curves of h
 igher genus correspond to non-geometric backgrounds of the M-theory compac
 tifications\, which are related to exotic branes. In particular\, the numb
 er of “special directions” of the exotic brane is equal to the genus o
 f the corresponding curve. In addition to predicting three new non-geometr
 ic backgrounds\, we discuss a relation between addition of curves in the d
 el Pezzo and the brane polarization effect.\n
