Sufficient connectivity conditions for rigidity of symmetric frameworks
Viktoria E. Kaszanitzky, Bernd Schulze
It is a famous result of Lovasz and Yemini (1982) that 6-connected graphs are rigid in the plane. This was recently improved by Jackson and Jordan (2009) who showed that 6-mixed co…

Rigid cylindrical frameworks with two coincident points
Bill Jackson, Viktoria Kaszanitzky, Anthony Nixon
We develop a rigidity theory for frameworks in which have two coincident points but are otherwise generic and only infinitesimal motions which are tangential to a fa…
