An improved bound for the rigidity of linearly constrained frameworks

Bill Jackson, Anthony Nixon, Shin-Ichi Tanigawa

We consider the problem of characterising the generic rigidity of bar-joint frameworks in $R^{d}$ in which each vertex is constrained to lie in a given affine subspace. The…

Flexible circuits in the $d$ -dimensional rigidity matroid

Georg Grasegger, Hakan Guler, Bill Jackson +1

A bar-joint framework $(G, p)$ in $R^{d}$ is rigid if the only edge-length preserving continuous motions of the vertices arise from isometries of $R^{d}$ . It is known…

Vertex Splitting, Coincident Realisations and Global Rigidity of Braced Triangulations

James Cruickshank, Bill Jackson, Shin-ichi Tanigawa

We give a short proof of a result of Jordan and Tanigawa that a 4-connected graph which has a spanning planar triangulation as a proper subgraph is generically globally rigid in R^…
