+ | **Strong Invariants in Real Enumerative Geometry** | ||
+ | |||
+ | Abstract: In the first lecture I will discuss a signed count of real lines on real projective hypersurfaces, | ||
+ | structures and in that sense is “strong invariant”. The simplest examples: a signed count of real lines on a real cubic surface gives 3, while a similar count on a real quintic 3-fold gives 15. In the other lectures I will stick to the case of real del Pezzo surfaces and discuss a generalization of the signed count of lines to a signed count of rational curves (involving some combinations of the Welschinger numbers). | ||
