On the connectivity of some complete intersections

Abstract

We show that the complement of a degree dd hypersurface in a projective complete intersection, whose defining equations have degrees strictly larger than dd, has a rational connectivity higher than expected. The key new feature is that a positivity result replaces the usual transversality conditions needed to get such connectivity results.
