DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ZAG/74/">Enu
 merating punctured log Gromov-Witten invariants from wall-crossing</a>\nby
  Hulya Arguz (Versailles Saint-Quentin-en-Yvelines University) as part of 
 ZAG (Zoom Algebraic Geometry) seminar\n\n\nAbstract\nPunctured log Gromov
 —Witten invariants of Abramovich—Chen--Gross—Siebert are obtained by
  counting of stable maps with prescribed tangency conditions (which are al
 lowed to be negative) relative to a not necessarily smooth divisor. In thi
 s talk we describe an algorithmic method to compute punctured log Gromov-W
 itten invariants of log Calabi-Yau varieties\, which are obtained by blowi
 ng-up of toric varieties along hypersurfaces on the toric boundary. For th
 is we use tropical geometry and wall-crossing computations. This is joint 
 work with Mark Gross (arxiv:2007.08347).\n
