  6. Sphere. A sphere is defined as the set of all points in three-dimensional Euclidean space that are located at a distance (the radius) from a given point (the center). Twice the radius is called the diameter, and pairs of points on the sphere on opposite sides of a diameter are called antipodes. Unfortunately, geometers and topologists adopt incompatible conventions for the meaning of.

Specifically: A 1-ball, a line segment, is the interior of a 0-sphere.A 2-ball, a disk, is the interior of a circle (1-sphere).A 3-ball, an ordinary ball, is the interior of a sphere (2-sphere) 2Sphere Ministry is a mission outreach to help people grow in their passion to serve Jesus and to cultivate a passion to share Jesus with our neighbors like the Bible illustration in Luke about the Good Samaritan

GROUP ACTIONS OF THE 2-SPHERE By GAVEN J. MARTIN' and RICHARD K. SKORA2 1. Introduction. In this paper we begin the classification of certain discrete groups of homeomorphisms of the 2-sphere. The groups we will consider are convergence groups which were first identified by F. Gehring and Martin [GM1]. These groups are a natural generalization. Thurston obtained a combinatorial characterization for generic branched self-coverings that preserve the orientation of the oriented 2-sphere by associating a planar graph to them [arXiv:1502.04760]. In this work, the Thurston result is generalized to any branched covering of the oriented 2-sphere. To achieve that the notion of local balance introduced by Thurston is generalized. As an.

2. One of the simplest ways to detect departure from CSR (complete spatial randomness -- uniform Poisson process) is by a quadrat test which extends straightforwardly to the case of the n-sphere. You can simply cut the sphere into smaller regions and calculate the expected versus observed number of points in each region and evaluate the test. Return the level at which the metric has approximately the given value. For example, ``s2sphere.AVG_EDGE.get_closest_level (0.1)`` returns the level at which the average cell edge length is approximately 0.1.
