DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Geolis/12/">
 Intrinsic Mirror Symmetry</a>\nby Mark Gross (Department of Pure Mathemati
 cs and Mathematical Statistics\, University of Cambridge) as part of Geome
 tria em Lisboa (IST)\n\n\nAbstract\nI will talk about joint work with Bern
 d Siebert\, proposing a general mirror construction for log Calabi-Yau pai
 rs\, i.e.\, a pair $(X\,D)$ with $D$ a "maximally degenerate" boundary div
 isor and $K_X+D=0$\, and for maximally unipotent degenerations of Calabi -
  Yau manifolds. We accomplish this by constructing the coordinate ring or 
 homogeneous coordinate ring respectively in the two cases\, using certain 
 kinds of Gromov-Witten invariants we call "punctured invariants"\, develop
 ed jointly with Abramovich and Chen.\n
