In mathematics, a cell is a finite regular polytope.

A parallelogram (parallelepiped) containing the minimum repeatable elements of a circle (sphere) packing.

The generalization of a Voronoi polygon to n dimensions for n>2.

A random polygon containing the origin (Kovalenko 1999).

The polyhedron resulting from letting each sphere in a sphere packing expand uniformly until it touches its neighbors on flat faces.

An elliptic function with no poles in a fundamental cell is a constant.

Rule 102 is one of the elementary cellular automaton rules introduced by Stephen Wolfram in 1983 (Wolfram 1983, 2002). It specifies the next color in a cell, depending on its ...

The ordinary differential equation (y^')^m=f(x,y) (Hille 1969, p. 675; Zwillinger 1997, p. 120).

The simplest class of one-dimensional cellular automata. Elementary cellular automata have two possible values for each cell (0 or 1), and rules that depend only on nearest ...

Let each sphere in a sphere packing expand uniformly until it touches its neighbors on flat faces. Call the resulting polyhedron the local cell. Then the local density is ...
