Liftings of surfaces in the plane
Oleg Karpenkov, Brigitte Servatius, Herman Servatius · 2025-05-25 · via math.CO updates on arXiv.org

In this note we provide a topological definition of Maxwell-Cremona liftings for non-planar frameworks of surfaces (both oriented and non-oriented). In the non-oriented case we give an estimate on the dimension of self-stresses, when the frameworks will posses a non-trivial lifting.
