Time-Like Isothermic Surfaces Associated to Grassmannian Systems
نویسندگان
چکیده
We establish that, as is the case with space-like isothermic surfaces, time-like isothermic surfaces in pseudo-riemannian space R n−j,j are associated to the O(n− j + 1, j + 1)/O(n− j, j)×O(1, 1)system. 2000 Mathematics Subject Classification: Primary 53A35; Secondary53C40.

Not yet Determined Manuscript-nr. Remarks on the Darboux Transform of Isothermic Surfaces
We study Darboux and Christooel transforms of isothermic surfaces in Euclidean space. These transformations play a signiicant role in relation to integrable system theory. Surfaces of constant mean curvature turn out to be special among all isothermic surfaces: their parallel constant mean curvature surfaces are Christooel and Darboux transforms at the same time. We prove | as a generalization ...
متن کاملDeformations of surfaces preserving conformal or similarity invariants
Constant mean curvature surfaces (abbriviated as CMC surfaces) in the space forms are typical examples of isothermic surfaces. Bonnet showed that every constant mean curvature surface admits a one-parameter family of isometric deformations preserving the mean curvature. A surface which admits such a family of deformations is called a Bonnet surface. Both the isothermic surfaces and Bonnet surfa...
متن کاملTableaux over Lie algebras, integrable systems and classical surface theory
Starting from suitable tableaux over finite dimensional Lie algebras, we provide a scheme for producing involutive linear Pfaffian systems related to various classes of submanifolds in homogeneous spaces which constitute integrable systems. These include isothermic surfaces, Willmore surfaces, and other classical soliton surfaces. Completely integrable equations such as the G/G0-system of Terng...
متن کاملIsothermic Surfaces: Conformal Geometry, Clifford Algebras and Integrable Systems
There is some novelty even to the classical theory which arises from the fact that isothermic surfaces are conformally invariant objects in contrast, for example, to the more familiar surfaces of constant Gauss or mean curvature. Thus we have to do with a second order, parabolic geometry which has its own flavour quite unlike Euclidean or Riemannian geometry. To compute effectively in this sett...
متن کاملA discrete version of the Darboux transform for isothermic surfaces
We study Christoffel and Darboux transforms of discrete isothermic nets in 4-dimensional Euclidean space: definitions and basic properties are derived. Analogies with the smooth case are discussed and a definition for discrete Ribaucour congruences is given. Surfaces of constant mean curvature are special among all isothermic surfaces: they can be characterized by the fact that their parallel c...
