On Konopelchenko's representation for surfaces in 4 dimensions
Frederic Helein
The purpose of this short note is to relate a representation formula due to the Author and P. Romon for Lagrangian surfaces (see math.DG/0009202) to a more general Weierstrass repr…
Problemes variationnels invariants par transformation conforme en dimension 2
Frederic Helein
This text proposes geometrical descriptions of all variational problems invariant by conformal transformations in two variables. First a characterisation in terms of C-Finsler mani…
Hamiltonian stationary Lagrangian surfaces in Hermitian symmetric spaces
Frederic Helein, Pascal Romon
This paper is the third of a series on Hamiltonian stationary Lagrangian surfaces. We present here the most general theory, valid for any Hermitian symmetric target space. Using we…
Hamiltonian stationary Lagrangian surfaces in C^2
Frederic Helein, Pascal Romon
We study Hamiltonian stationary Lagrangian surfaces in C^2, i.e. Lagrangian surfaces in C^2 which are stationary points of the area functional under smooth Hamiltonian variations.…
