Cauchy's Arm Lemma on a Growing Sphere
نویسندگان
چکیده
We propose a variant of Cauchy’s Lemma, proving that when a convex chain on one sphere is redrawn (with the same lengths and angles) on a larger sphere, the distance between its endpoints increases. The main focus of this work is a comparison of three alternate proofs, to show the links between Toponogov’s Comparison Theorem, Legendre’s Theorem and Cauchy’s Arm Lemma.

Uniqueness theorems for polyhedra.
In 1813, Cauchy2 gave the first proof of the theorem that two closed convex polyhedra in three-dimensional space are congruent if their faces are congruent in pairs and are joined to each other in the same order: in effect, the a priori possibility of rotations of the faces about the edges-which are obviously seen to be possible for some easily constructed open polyhedra-cannot occur for closed...
متن کاملCasimir Energy of a Spherical Shell
The Casimir energy for a conducting spherical shell of radius a is computed using a direct mode summation approach. An essential ingredient is the implementation of a recently proposed method based on Cauchy's theorem for an evaluation of the eigenfrequencies of the system. It is shown, however, that this earlier calculation uses an improper set of modes to describe the waves exterior to the sp...
متن کاملCauchy Rigidity of C -polyhedra
We generalize Cauchy’s celebrated theorem on the global rigidity of convex polyhedra in Euclidean 3-space E to the context of circle polyhedra in the 2-sphere S. We prove that any two convex and bounded non-unitary c-polyhedra with Möbiuscongruent faces that are consistently oriented are Möbius-congruent. Our result implies the global rigidity of convex inversive distance circle packings as wel...
متن کاملRigidity and Energy
Suppose one holds two sticks in the form of a cross in one hand, and places a rubber band in tension around the four ends. When it is released, it comes to rest in the shape of a convex quadrilateral in a plane. It always returns to the same shape, no matter how it is distorted, as long as the ends do not slip, and the rubber band does not break. This is a very simple example of a "rigid" frame...
متن کاملA Borsuk-Ulam Equivalent that Directly Implies Sperner's Lemma
We show that Fan’s 1952 lemma on labelled triangulations of the n-sphere with n + 1 labels is equivalent to the Borsuk–Ulam theorem. Moreover, unlike other Borsuk–Ulam equivalents, we show that this lemma directly implies Sperner’s Lemma, so this proof may be regarded as a combinatorial version of the fact that the Borsuk–Ulam theorem implies the Brouwer fixed-point theorem, or that the Lustern...
