Constructing solutions to the Björling problem for isothermic surfaces by structure preserving discretization
Ulrike Bücking, Daniel Matthes
In this article, we study an analog of the Björling problem for isothermic surfaces (that are more general than minimal surfaces): given a real analytic curve in ${\mathbb R}^3…

Quasiconformal distortion of projective transformations and discrete conformal maps
Stefan Born, Ulrike Bücking, Boris Springborn
We consider the quasiconformal dilatation of projective transformations of the real projective plane. For non-affine transformations, the contour lines of dilatation form a hyperbo…
