The Isostatic Conjecture Connelly, Robert


We show that a jammed packing of disks with generic radii, in a generic container, is such that the minimal number of contacts occurs, and for the graph of the packing, there is only one equilibrium stress up to scaling. We also point out some connections to packings with different radii and results in the theory of circle packings whose graph forms a triangulation of a given topological surface. Joint work with Evan Solomonides and Maria Yampolskaya.
