✦ Synopsis
We study the conformal geometry of an oriented space-like surface in three-dimensional Lorentzian space forms. After introducing the conformal compactification of the Lorentzian space forms, we define the conformal Gauss map which is a conformally invariant two parameter family of oriented spheres. We use the area of the conformal Gauss map to define the Willmore functional and derive a Bemstein type theorem for parabolic Willmore surfaces. Finally, we study the stability of maximal surfaces for the Willmore functional.

In this paper we introduce s-degenerate curves in Lorentzian space forms as those ones whose derivative of order s is a null vector provided that s > 1 and all derivatives of order less than s are space-like (see the exact definition in Section 2). In this sense classical null curves are 1-degenerat
There are three types of hypersurfaces in a pseudoconformal space C; of Lorentzian signature: spacelike, timelike, and lightlike. These three types of hypersurfaces are considered in parallel. Spacelike hypersurfaces are endowed with a proper conformal structure, and timelike hypersurfaces are endow
In the description of the extrinsic geometry of the string world sheet regarded as a conformal immersion of a \(2-\mathrm{d}\) surface in \(R^{3}\), it was previously shown that restricting ourselves to surfaces with \(h \sqrt{g}=1\), where \(h\) is the mean scalar curvature and \(g\) is the determi
