We consider a new stratification of the space of configurations of $d$ marked points on the complex plane. Recall, that this space can be differently interpreted as the space $Dpol_{d}$ of degree $d>1$ complex, monic polynomials with distinct roots, the sum of which is 0. A stratum $A_{\sigma}$, is the set of polynomials having $P^{-1}(\mathbb{R}\cup\imath\mathbb{R})$ in the same isotopy class, relative to their asymptotic directions. We show that this stratification is topological, and its…

Hidden symmetries of the Grothendieck--Teichm\"uller group

. We consider the Grothendieck–Teichmüller group under a new aspect. Using real algebraic geometry and web theory we show that it preserves dihedral symmetry relations, present in the fundamental

Decomposition in Coxeter-chambers of the configuration space of $d$ marked points on the complex plane

In this paper we investigate a new decomposition in Coxeter-chambers of the $d$-th unordered configuration space of the complex plane space, using its natural relation with the space $Dpol_d$ of

Nonpositive curvature of blow-ups

Consider the following situation: M C is a complex manifold of complex dimension n, and D C is a union of smooth complex codimension-one submanifolds (i.e., D C is a smooth divisor). Examples of this

Configuration spaces with summable labels

An n-monoid is the appropriate extension of an A ∞-space for the theory of n-fold loop spaces. We define spaces of configurations on n-manifolds with summable labels in partial n-monoids. In

The cohomology ring of the real locus of the moduli space of stable curves of genus 0 with marked points

We compute the Poincare polynomial and the cohomology algebra with rational coefficients of the manifold M_n of real points of the moduli space of algebraic curves of genus 0 with n labeled points.

Functors of Artin rings

0. Introduction. In the investigation of functors on the category of preschemes, one is led, by Grothendieck [3], to consider the following situation. Let A be a complete noetherian local ring, ,u

Cohomology of Artin groups of type z An, Bn and applications

We consider two natural embeddings between Artin groups: the group Gz An 1 of type z An 1 embeds into the group GBn of type Bn ; GBn in turn embeds into the classical braid group BrnC1WD GAn of type

Operads and knot spaces

Let Em denote the space of embeddings of the interval I = [?1,1] in the cube Im with endpoints and tangent vectors at those endpoints fixed on opposite faces of the cube, equipped with a homotopy

Spaces of smooth embeddings, disjunction and surgery

We describe progress in the theory of smooth embeddings over more than 50 years, starting with Whitney’s embedding theorem, continuing with the generalized Whitney tricks of Haefliger and Dax, early

Combinatorial Cellular Decompositions for the Space of Complex Coefficient Polynomials

We describe a classification of degree n complex coefficient polynomials with respect to combinatorial patterns that arise from the two real algebraic curves obtained as the zero sets for their real
