Tameness of Holomorphic Closure Dimension in a Semialgebraic Set

Given a semianalytic set S in Cn and a point p ∈ S, there is a unique smallest complex-analytic germ Xp which contains Sp, called the holomorphic closure of Sp. We show that if S is semialgebraic then Xp is a Nash germ, for every p, and S admits a semialgebraic filtration by the holomorphic closure dimension. As a consequence, every semialgebraic subset of a complex vector space admits a semial...

Tameness of Complex Dimension in a Real Analytic Set

Given a real analytic set X in a complex manifold and a positive integer d, denote by Ad the set of points p in X at which there exists a germ of a complex analytic set of dimension d contained in X. It is proved that Ad is a closed semianalytic subset of X.

On the Holomorphic Closure Dimension of Real Analytic Sets

Given a real analytic (or, more generally, semianalytic) set R in C (viewed as R), there is, for every p ∈ R̄, a unique smallest complex analytic germ Xp that contains the germ Rp. We call dimC Xp the holomorphic closure dimension of R at p. We show that the holomorphic closure dimension of an irreducible R is constant on the complement of a closed proper analytic subset of R, and discuss the re...

The dimension of semialgebraic subdifferential graphs

A corollary of a celebrated theorem of Minty is that the subdifferential graph of a closed convex function on Rn has uniform local dimension n. In contrast, there exist nonconvex closed functions whose subdifferentials have large graphs. We consider how far Minty’s corollary extends to functions that are nonconvex but semi-algebraic. © 2011 Elsevier Ltd. All rights reserved.

Two-dimensional projectively-tameness over Noetherian domains of dimension one

In this paper all coordinates in two variables over a Noetherian Q-domain of Krull dimension one are proved to be projectively tame. In order to do this, some results concerning projectively-tameness of polynomials in general are shown. Furthermore, we deduce that all automorphisms in two variables over a Noetherian reduced ring of dimension zero are tame.
