On Lipschitz rigidity of complex analytic sets

Algebraic Geometry 2018-03-07 v3 Complex Variables

Abstract

We prove that any complex analytic set in Cn\mathbb{C}^n which is Lipschitz normally embedded at infinity and has tangent cone at infinity that is a linear subspace of Cn\mathbb{C}^n must be an affine linear subspace of Cn\mathbb{C}^n itself. No restrictions on the singular set, dimension nor codimension are required. In particular, a complex algebraic set in Cn\mathbb{C}^n which is Lipschitz regular at infinity is an affine linear subspace.
