Bar-and-joint rigidity on the moment curve coincides with cofactor rigidity on a conic

چکیده
We show that, for points along the moment curve, bar-and-joint rigidity matroid and hyperconnectivity coincide, that both coincide with \(C^{d-2}_{d-1}\)-cofactor of any (non-degenerate) conic in plane. For dimension two, having curve is no loss generality. also restricted to bipartite graphs, freer than matroid.Mathematics Subject Classifications: 52C25, 52B40Keywords: Rigidity, hyperconnectivity, cofactor

Infinitesimal Rigidity of Symmetric Bar-Joint Frameworks
We propose new symmetry-adapted rigidity matrices to analyze the infinitesimal rigidity of arbitrary-dimensional bar-joint frameworks with Abelian point group symmetries. These matrices define new symmetry-adapted rigidity matroids on grouplabeled quotient graphs. Using these new tools, we establish combinatorial characterizations of infinitesimally rigid two-dimensional bar-joint frameworks wh...
متن کاملOn Global Rigidity and Universal Rigidity of Generic Bar Frameworks with Few Vertices
Gale transform was successfully used to classify polytopes with few vertices; that is, r-dimensional polytopes with r + k vertices, where k is small. In this paper, we use Gale transform to classify r-dimensional generic bar frameworks with r + k vertices, where k ≤ 4; as universally rigid, globally rigid or nonglobally rigid.
متن کاملThe Almost Periodic Rigidity of Crystallographic Bar-Joint Frameworks
A crystallographic bar-joint framework, C in R, is shown to be almost periodically infinitesimally rigid if and only if it is strictly periodically infinitesimally rigid and the rigid unit mode (RUM) spectrum, Ω(C), is a singleton. Moreover, the almost periodic infinitesimal flexes of C are characterised in terms of a matrix-valued function, ΦC(z), on the d-torus, T, determined by a full rank t...

On the Infinitesimal Rigidity of Bar-and-Slider Frameworks
A bar-slider framework is a bar-joint framework a part of whose joints are constrained by using line-sliders. Such joints are allowed to move only along the sliders. Streinu and Theran proposed a combinatorial characterization of the infinitesimal rigidity of generic bar-slider frameworks in two dimensional space. In this paper we propose a generalization of their result. In particular, we prov...
