Stressability of Semi-Discrete Frameworks
Oleg Karpenkov, Christian Müller, Anna Pratoussevitch
In this paper we study the stressability of semi-discrete frameworks in the plane which are generated by a discrete sequence of smooth curves. We characterize their stressability p…

Discrete Lorentz surfaces and s-embeddings II: maximal surfaces
Niklas Christoph Affolter, Felix Dellinger, Christian Müller +2
S-embeddings were introduced by Chelkak as a tool to study the conformal invariance of the thermodynamic limit of the Ising model. Moreover, Chelkak, Laslier and Russkikh introduce…

Klein-Arnold tensegrities
Oleg Karpenkov, Fatemeh Mohammadi, Christian Müller +1
In this paper, we introduce new classes of infinite and combinatorially periodic tensegrities, derived from algebraic multidimensional continued fractions in the sense of F. Klein.…
