Codimension One Spheres Which Are Null Homotopic
Grove and Halperin [3] introduced a notion of taut immersions. Terng and Thorbergsson [5] give a slightly different definition and showed that taut immersions are a simultaneous generalization of taut immersions of manifolds into Euclidean spaces or spheres, and some interesting embeddings constructed by Bott and Samelson [1]. They go on to prove many theorems about such immersions. One particu...
متن کاملTangent Hyperplanes to Subriemannian Balls
We examine the existence of tangent hyperplanes to subriemannian balls. Strictly abnormal shortest paths are allowed.
متن کاملCovering a Ball with Smaller Equal Balls in Rn
We give an explicit upper bound of the minimal number of balls of radius 1/2 which form a covering of a ball of radius T > 1/2 in R, n > 2.
متن کاملTangent Spheres and Triangle Centers
1. TANGENT SPHERES. Any four mutually tangent spheres determine six points of tangency. We say that a pair of tangencies {ti , t j } is opposite if the two spheres determining ti are distinct from the two spheres determining t j . Thus the six tangencies are naturally grouped into three opposite pairs, corresponding to the three ways of partitioning the four spheres into two pairs. Altshiller-C...
متن کاملKnotted Spheres and Graphs in Balls
Given a properly embedded graph Γ in a ball B and a punctured sphere Σ properly embedded in B − Γ we examine the conditions on Γ that are necessary to assure that Σ is boundary parallel.
