Coincident-point rigidity in normed planes
Sean Dewar, John Hewetson, Anthony Nixon
A bar-joint framework is the combination of a graph and a map assigning positions, in some space, to the vertices of . The framework is rigid if every edge-lengt…
Flexing infinite frameworks with applications to braced Penrose tilings
Sean Dewar, Jan Legerský
A planar framework -- a graph together with a map of its vertices to the plane -- is flexible if it allows a continuous deformation preserving the distances between adjacent vertic…
Infinitesimal rigidity and prestress stability for frameworks in normed spaces
Sean Dewar
A (bar-and-joint) framework is a set of points in a normed space with a set of fixed distance constraints between them. Determining whether a framework is locally rigid - i.e. whet…
Generalised rigid body motions in non-Euclidean planes with applications to global rigidity
Sean Dewar, Anthony Nixon
A bar-joint framework in a (non-Euclidean) real normed plane is the combination of a finite, simple graph and a placement of the vertices in . A framework $(…
Maximum likelihood thresholds via graph rigidity
Daniel Irving Bernstein, Sean Dewar, Steven J. Gortler +3
The maximum likelihood threshold (MLT) of a graph is the minimum number of samples to almost surely guarantee existence of the maximum likelihood estimate in the corresponding…
