DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OBAGS/80/">B
 PS polynomials and Welschinger invariants</a>\nby Pierrick Bousseau (Oxfor
 d) as part of ODTU-Bilkent Algebraic Geometry Seminars\n\n\nAbstract\nUsin
 g tropical geometry\, Block-Göttsche defined polynomials with the remarka
 ble property to interpolate between Gromov-Witten counts of complex curves
  and Welschinger counts of real curves in toric del Pezzo surfaces. I will
  describe a generalization of Block-Göttsche polynomials to arbitrary\, n
 ot-necessarily toric\, rational surfaces and propose a conjectural relatio
 n with refined Donaldson-Thomas invariants. This is joint work with Hulya 
 Arguz.\n
