On Affine Real Cubic Surfaces
Sergey Finashin, Viatcheslav Kharlamov
We prove that the space of affine, transversal at infinity, non-singular real cubic surfaces has 15 connected components. We give a topological criterion to distinguish them and sh…

On wall-crossing invariance of certain sums of Welschinger numbers
Sergey Finashin, Viatcheslav Kharlamov
We continue our quest for real enumerative invariants not sensitive to changing the real structure and extend the construction we uncovered previously for counting curves of anti-c…
