In this paper we give for any integer l ≥ 2 a numerical criterion ensuring the existence of a chain of length l of lines through two general points of an irreducible variety X ⊂ PN, involving the degrees and the number of homogeneous polynomials defining X.

Abstract

In this paper we give for any integer l ≥ 2 a numerical criterion ensuring the existence of a chain of length l of lines through two general points of an irreducible variety X ⊂ PN, involving the degrees and the number of homogeneous polynomials defining X. We show that our criterion is sharp. © 2012 Springer Science+Business Media Dordrecht.
