Non-crossing frameworks with non-crossing reciprocals
David Orden, Guenter Rote, Francisco Santos +3
We study non-crossing frameworks in the plane for which the classical reciprocal on the dual graph is also non-crossing. We give a complete description of the self-stresses on non-…

Planar Minimally Rigid Graphs and Pseudo-Triangulations
Ruth Haas, David Orden, Guenter Rote +6
Pointed pseudo-triangulations are planar minimally rigid graphs embedded in the plane with pointed vertices (adjacent to an angle larger than 180 degrees. In this paper we prove th…
