 >\nby Pierrick Bousseau (University of Georgia) as part of Stanford algebr
 aic geometry seminar\n\nLecture held in 383-N.\n\nAbstract\nUsing tropical
  geometry\, Block-Göttsche defined polynomials with the remarkable proper
 ty to interpolate between Gromov-Witten counts of complex curves and Welsc
 hinger counts of real curves in toric del Pezzo surfaces. I will describe 
 a generalization of Block-Göttsche polynomials to arbitrary\, not-necessa
 rily toric\, rational surfaces and propose a conjectural relation with ref
 ined Donaldson-Thomas invariants. This is joint work in progress with Huly
 a Arguz.\n
