We generalize results by Wakabayashi and Orevkov about rational cuspidal curves on the projective plane to that on ℚ-homology projective planes. It turns out that the result is exactly the same as the projective plane case under suitable assumptions. We also provide examples which demonstrate sharpness of the results. The ambient surface is singular in these examples.

Abstract


We generalize results by Wakabayashi and Orevkov about rational cuspidal curves on the projective plane to that on ℚ-homology projective planes. It turns out that the result is exactly the same as the projective plane case under suitable assumptions. We also provide examples which demonstrate sharpness of the results. The ambient surface is singular in these examples.
