On the codimension of the singular locus

preprint2020arXivOpen access

Abstract

Let kk be a field and VV an kk-vector space. For a family Pˉ={Pi}1≤i≤c,\bar P=\{ P_i\}_{1\leq i\leq c}, of polynomials on VV, we denote by XPˉ⊂V\mathbb X _{\bar P}\subset V the subscheme defined by the ideal generated by Pˉ \bar P. We show the existence of γ(c,d)γ(c,d) such that the varieties XPˉ\mathbb X_{\bar P} are smooth outside of codimension mm, if deg(Pi)≤d(P_i)\leq d and rank (strength) rnc(Pˉ)≥γ(d,c)(1+m)γ(d,c)r_{nc}(\bar P)\geq γ(d,c) (1+m)^{γ(d,c)}.
