Resumen de On wall-crossing invariance of certain sums of Welschinger numbers

S. 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-canonical degree ≤ 2 on del Pezzo surfaces with K2 = 1 to curves of any anti-canonical degree and on any del Pezzo surfaces of degree K2 ≤ 3.
