Abstract

We study effective divisors D on surfaces with H0(OD) = k and H1(OD) = H0(OD(D)) = 0. We give a numerical criterion for such divisors, following a general investigation of negativity, rigidity and connectivity properties. Examples include exceptional loci of rational singularities, and spherelike divisors.
