| Abstract: | We refine results of 6] and 10] which relate local invariants – Seshadri constants – of ample line bundles on surfaces to the global geometry – fibration structure. We show that the same picture emerges when looking at Seshadri constants measured at any finite subset of the given surface (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim) |
