Combined count of real rational curves of canonical degree 2 on real del Pezzo surfaces with $K^{2} = 1$

Sergey Finashin, Viatcheslav Kharlamov

We propose two systems of "intrinsic" signs for counting such curves. In both cases the result acquires an exceptionally strong invariance property: it does not depend on the choic…

Two kinds of real lines on real del Pezzo surfaces of degree 1

Sergey Finashin, Viatcheslav Kharlamov

We show how the real lines on a real del Pezzo surface of degree 1 can be split into two species, elliptic and hyperbolic, via a certain distinguished, intrinsically defined, Pin-s…
