Generalized Weierstrass representation for surfaces in Heisenberg spaces

open access: yesDifferential Geometry and its Applications, 2012
It is well-known that constant mean curvature surfaces immersed in Euclidean \(3\)-space admit an integral representation in terms of their Gauss maps which resembles the classical Weierstrass representation for minimal surfaces, and these also have harmonic Gauss map with target given by some Grassmannian space.

A generalized Weierstrass representation of Lorentzian surfaces in ℝ2,2 and applications [PDF]

open access: yesInternational Journal of Geometric Methods in Modern Physics, 2016
We give a generalized Weierstrass formula for a Lorentz surface conformally immersed in the four-dimensional space [Formula: see text] using spinors and Lorentz numbers. We also study the immersions of a Lorentzian surface in the Anti-de Sitter space (a pseudo-sphere in [Formula: see text]): we give a new spinor representation formula and deduce the ...

A twistorial interpretation of the Weierstrass representation formulae [PDF]

open access: yes
The theory of minimal surfaces represents an important chapter\ud in the study of global analysis and remains a testing ground for our\ud understanding of the non-linear partial differential equations of\ud geometry. Perhaps its greatest charm lies in its mercurial avoidance\ud of isolation.
