Weierstrass i l'aproximació uniforme

, 2013
Presentem el teorema d'aproximació uniforme de funcions contínues per polinomis en el marc del punt de vista de Weierstrass sobre la construcció de l'anàlisi a partir de la representació de les funcions com a sumes de sèries de potències o de funcions ...

Weierstrass representation of Lagrangian surfaces in four-dimensional space using spinors and quaternions

, 2000
International audienceWe derive a Weierstrass-type formula for conformal Lagrangian immersions in Euclidean 4-space, and show that the data satisfies an equation similar to Dirac equation with complex potential.

Bilinear operators and the power series for the Weierstrass $\sigma$ function

, 2000
We use the bilinear operator formalism to derive a new representation of the power series for the Weierstrass s function.

Faithfulness of actions on Riemann-Roch spaces

, 2015
Given a faithful action of a finite group G on an algebraic curve X of genus g > 1, we give explicit criteria for the induced action of G on the Riemann-Roch space H^0(X,O_X(D)) to be faithful, where D is a G-invariant divisor on X of degree at least ...

The discrete Dirac operator and the discrete generalized Weierstrass representation in pseudo-Euclidean spaces

, 2010
In this thesis we consider the problem of finding a integrable discretization of the Dirac operator. We show that an appropriate deformation of the spectral properties of the eigen-function of the smooth Dirac operator leads to a discrete integrable ...

Representation formulas and far-field behavior of time-periodic flow past a body [PDF]

This paper is concerned with integral representations and asymptotic expansions of solutions to the time-periodic incompressible Navier-Stokes equations for fluid flow in the exterior of a rigid body that moves with constant velocity.
