The Dehn invariants of the Bricard octahedra
نویسنده
چکیده
We prove that the Dehn invariants of any Bricard octahedron remain constant during the flex and that the Strong Bellows Conjecture holds true for the Steffen flexible polyhedron. Mathematics Subject Classification (2000): 52C25.

Higher Order Flexibility of Octahedra
More than hundred years ago R. Bricard determined all continuously ex-ible octahedra. On the other hand, also the geometric characterization of rst-order exible octahedra has been well known for a long time. The objective of this paper is to analyze the cases between, i.e., octahedra which are innnitesimally exible of order n > 1 but not continuously exible. We prove explicit necessary and suuc...
متن کاملOn Quasiperiodic Space Tilings, Inflation, and Dehn Invariants
Abstract We introduce Dehn invariants as a useful tool in the study of the inflation of quasiperiodic space tilings. The tilings by “golden tetrahedra” are considered. We discuss how the Dehn invariants can be applied to the study of inflation properties of the six golden tetrahedra. We also use geometry of the faces of the golden tetrahedra to analyze their inflation properties. We give the in...
متن کاملGauge theoretic invariants of Dehn . . .
1 irreducible SU2 representations depends in a subtle way on the perturbation. To compensate , Walker deened a correction term using integral symplectic invariants of the reducible i.e. abelian representations. This correction term can alternatively be viewed as a sum of diierences between the Maslov index and a nonintegral term 88 or as a sum of U1 rho invariants 277. In 55, the objects of stu...
متن کاملInvariants of Closed 3–Manifolds via Nullhomotopic Filling Dehn Spheres
We provide a calculus for the presentation of closed 3–manifolds via nullhomotopic filling Dehn spheres and we use it to define an invariant of closed 3–manifolds by applying the state-sum machinery. As a potential application of this invariant, we show how to get lower bounds for the Matveev complexity of P–irreducible closed 3–manifolds. We also describe an easy algorithm for constructing a n...
متن کاملSelf-motions of parallel manipulators associated with flexible octahedra
A Stewart Gough (SG) platform is a parallel manipulator consisting of a moving platform, which is connected via six Spherical-Prismatical-Spherical (SPS) legs with the base. Moreover a SG platform is called planar if the six platform anchor points mi (i = 1, . . . ,6) are located in a plane and if the corresponding base anchor points Mi are coplanar as well (see Fig. 1a). Note that a SG platfor...
