چکیده
Let r = SL(n, Il) or any subgroup of finite index. Then the action of r on Tn by automorphisms is infinitesimally rigid for n ;::: 7, i.e., the cohomology H I (r, Vec(Tn)) = 0 , where Vec(Tn) denotes the module of COO vector fields on Tn .

Finite and Infinitesimal Rigidity with Polyhedral Norms
We characterise finite and infinitesimal rigidity for bar-joint frameworks in R with respect to polyhedral norms (i.e. norms with closed unit ball P a convex d-dimensional polytope). Infinitesimal and continuous rigidity are shown to be equivalent for finite frameworks in R which are well-positioned with respect to P. An edge-labelling determined by the facets of the unit ball and placement of ...
متن کاملCrystal frameworks, symmetry and affinely periodic flexes
Symmetry equations are obtained for the rigidity matrices associated with various forms of infinitesimal flexibility for an idealised bond-node crystal framework C in R. These equations are used to derive symmetry-adapted Maxwell–Calladine counting formulae for periodic self-stresses and affinely periodic infinitesimal mechanisms. The symmetry equations also lead to general Fowler–Guest formula...
متن کاملInfinitesimal Weak Rigidity, Formation Control of Three Agents, and Extension to 3-dimensional Space
In this paper, we introduce new concepts of weak rigidity matrix and infinitesimal weak rigidity for planar frameworks. The weak rigidity matrix is used to directly check if a framework is infinitesimally weakly rigid while previous work can check a weak rigidity of a framework indirectly. An infinitesimal weak rigidity framework can be uniquely determined up to a translation and a rotation (an...
متن کاملInfinite bar-joint frameworks, crystals and operator theory
A theory of flexibility and rigidity is developed for general infinite bar-joint frameworks (G, p). Determinations of nondeformability through vanishing flexibility are obtained as well as sufficient conditions for deformability. Forms of infinitesimal flexibility are defined in terms of the operator theory of the associated infinite rigidity matrix R(G, p). The matricial symbol function of an ...
متن کاملRigidity of Graph Joins and Hendrickson's Conjecture
Whiteley [9] gives a complete characterization of the infinitesimal flexes of complete bipartite frameworks. Our work generalizes a specific infinitesimal flex to include joined graphs, a family of graphs that contain the complete bipartite graphs. We use this characterization to identify new families of counterexamples, including infinite families, in R and above to Hendrickson’s conjecture on...
