Circle packing on sphere
WebPacking circles in a two-dimensional geometrical form such as a unit square or a unit-side triangle is the best known type of extremal planar geometry problems . Herein, the … In geometry, a sphere packing is an arrangement of non-overlapping spheres within a containing space. The spheres considered are usually all of identical size, and the space is usually three-dimensional Euclidean space. However, sphere packing problems can be generalised to consider unequal spheres, spaces of other dimensions (where the problem becomes circle packing in two dimensions, or hypersphere packing in higher dimensions) or to non-Euclidean spaces such as hy…

WebIt belongs to a class of optimization problems in mathematics, which are called packing problems and involve attempting to pack objects together into containers. Circle packing in a circle is a two-dimensional packing problem to pack unit circles into the smallest possible larger circle. See Circle packing in a circle. In geometry, circle packing is the study of the arrangement of circles (of equal or varying sizes) on a given surface such that no overlapping occurs and so that no circle can be enlarged without creating an overlap. The associated packing density, η, of an arrangement is the proportion of the surface covered by the … See more In the two-dimensional Euclidean plane, Joseph Louis Lagrange proved in 1773 that the highest-density lattice packing of circles is the hexagonal packing arrangement, in which the centres of the circles are … See more Packing circles in simple bounded shapes is a common type of problem in recreational mathematics.
