A family of irreducible free divisors in P^2 [PDF]

open access: yes, 2014
An infinite family of irreducible homogeneous free divisors in $K[x, y, z]$ is constructed. Indeed, we identify sets of monomials $X$ such that the general polynomial supported on $X$ is a free divisor.Comment: comments are ...

A geometric definition of Gabrielov numbers

open access: yes, 2013
Gabrielov numbers describe certain Coxeter-Dynkin diagrams of the 14 exceptional unimodal singularities and play a role in Arnold's strange duality. In a previous paper, the authors defined Gabrielov numbers of a cusp singularity with an action of a ...

General elements of an m-primary ideal on a normal surface singularity [PDF]

open access: yes, 2003
In this paper, we show how to apply a theorem by L\^e D.T. and the author about linear families of curves on normal surface singularities to get new results in this area.

Strange duality of weighted homogeneous polynomials

open access: yes, 2010
We consider a mirror symmetry between invertible weighted homogeneous polynomials in three variables. We define Dolgachev and Gabrielov numbers for them and show that we get a duality between these polynomials generalizing Arnold's strange duality ...

Hodge-type integrals on moduli spaces of admissible covers

open access: yes, 2007
We study Hodge Integrals on Moduli Spaces of Admissible Covers. Motivation for this work comes from Bryan and Pandharipande's recent work on the local GW theory of curves, where analogouos intersection numbers, computed on Moduli Spaces of Relative ...

Testing Lipschitz non normally embedded complex spaces

open access: yes, 2018
We introduce a sectional criterion for testing if complex analytic germs $(X,0) \subset (\bC^n, 0)$ are Lipschitz non normally embedded.Comment: title changed; more introduction.

Normal crossing properties of complex hypersurfaces via logarithmic residues

open access: yes, 2014
We introduce a dual logarithmic residue map for hypersurface singularities and use it to answer a question of Kyoji Saito. Our result extends a theorem of L\^e and Saito by an algebraic characterization of hypersurfaces that are normal crossing in ...

Canonical contact structures on some singularity links

open access: yes, 2014
We identify the canonical contact structure on the link of a simple elliptic or cusp singularity by drawing a Legendrian handlebody diagram of one of its Stein fillings.

Gap conjecture for 3-dimensional canonical thresholds

open access: yes, 2008
We prove that the interval $(5/6, 1)$ contains no 3-dimensional canonical thresholds.Comment: 8 pages, latex, one reference is ...

Fundamental Domains in Lorentzian Geometry [PDF]

open access: yes, 2004
We consider discrete subgroups Gamma of the simply connected Lie group SU~(1,1), the universal cover of SU(1,1), of finite level, i.e. the subgroup intersects the centre of SU~(1,1) in a subgroup of finite index, this index is called the level of the ...
