WebLet G(p)be a globally rigid generic bar-and-joint framework inRd.Then either G is a complete graph on at most d+1vertices, or (i)the graph G is(d+1)-vertex-connected, and (ii)the framework G(p)is redundantly inﬁnitesimally rigid inRd. Note that redundant rigidity is a generic property. WebGlobal rigidity of frameworks and graphs is a well-studied area of rigidity theory with a number of applications, including the localization problem of sensor networks. Motivated by this application we consider the new notion of unit ball global rigidity, which can be defined similarly, except that ( G, p) as well as ( G, q) are required to be ...
