Abstract
Serre's nonnegativity conjecture for intersection multiplicities has recent ly been proven by O. Gabber. In this paper we investigate Serre's positivit y conjecture using the methods which he developed. We show in particular th at the positivity conjecture has implications for properties of symbolic po wers of prime ideals in regular local rings.
