Abstract
Numerically positive line bundles on a complex projective smooth algebraic surfaceS are studied. In particular for any such line bundleL ∈ Pic(S) we prove the following facts: (i)g(L) ≥ 0 and (ii)L is ample ifg(L) ≤ 1,g standing for the arithmetic genus. Some applications are discussed. We also investigate numerically positive non-ample line bundlesL withg(L)=2.
