Abstract

We present an intersection-theoretic formula concerning curves on projective surfaces in terms of lattices with special emphasis on minimal resolutions of \({\mathbb {Q}}\)-homology projective planes. This formula can be used to detect the existence/nonexistence of curves with given intersection properties.

Keywords
