A linking invariant for algebraic curves [PDF]

open access: yesL’Enseignement Mathématique, 2020
We construct a topological invariant of algebraic plane curves, which is in some sense an adaptation of the linking number of knot theory. This invariant is shown to be a generalization of the \mathcal I -invariant of line arrangements developed by ...

Hall algebras and curve-counting invariants [PDF]

open access: yesJournal of the American Mathematical Society, 2011
We use Joyce’s theory of motivic Hall algebras to prove that reduced Donaldson-Thomas curve-counting invariants on Calabi-Yau threefolds coincide with stable pair invariants and that the generating functions for these invariants are Laurent expansions of rational functions.

Explicit travelling waves and invariant algebraic curves

open access: yesNonlinearity, 2015
In this paper we introduce a precise definition of algebraic traveling wave solution for general n-th order partial differential equations. All examples of explicit traveling waves known by the authors fall in this category. Our main result proves that algebraic traveling waves exist if and only if an associated n- dimensional first order ordinary ...

Invariants of algebraic curves and topological expansion [PDF]

open access: yesCommunications in Number Theory and Physics, 2007
For any arbitrary algebraic curve, we define an infinite sequence of invariants. We study their properties, in particular their variation under a variation of the curve, and their modular properties. We also study their limits when the curve becomes singular.

Wetting, Algebraic Curves, and Conformal Invariance

open access: yesPhysical Review Letters
Recent studies of wetting in a two-component square-gradient model of interfaces in a fluid mixture, showing three-phase bulk coexistence, have revealed some highly surprising features. Numerical results show that the density profile paths, which form a tricuspid shape in the density plane, have curious geometric properties, while conjectures for the ...

Invariant hypercomplex structures and algebraic curves

open access: yesMathematische Nachrichten, 2022
AbstractWe show that ‐invariant hypercomplex structures on (open subsets) of regular semisimple adjoint orbits in correspond to algebraic curves C of genus , equipped with a flat projection of degree k, and an antiholomorphic involution covering the antipodal map on .

The method of Puiseux series and invariant algebraic curves [PDF]

open access: yesCommunications in Contemporary Mathematics, 2021
An explicit expression for the cofactor related to an irreducible invariant algebraic curve of a polynomial dynamical system in the plane is derived. A sufficient condition for a polynomial dynamical system in the plane to have a finite number of irreducible invariant algebraic curves is obtained.
