arXiv:1910.08816

Abstract

We introduce augmented and restricted base loci of cycles and we study the positivity properties naturally defined by these base loci.

15 pages; v2: minor change adding the case k=n-1; v3: major improvement following referee's indication of using push-forwards of complete intersections under finite flat maps and how this allows to extend the results. The main theorem now holds for any k and so do its consequences. To appear on the Annales de l'Institut Fourier
