Generic Rigidity with Forced Symmetry and Sparse Colored Graphs

  • Justin Malestein
  • Louis Theran
Part of the Fields Institute Communications book series (FIC, volume 70)


We review some recent results in the generic rigidity theory of planar frameworks with forced symmetry, giving a uniform treatment to the topic. We also give new combinatorial characterizations of minimally rigid periodic frameworks with fixed-area fundamental domain and fixed-angle fundamental domain.
