Dixon's elliptic functions

From Wikipedia, the free encyclopedia

In mathematics, Dixon's elliptic functions, are two doubly periodic meromorphic functions on the complex plane that have regular hexagons as repeating units: the plane can be tiled by regular hexagons in such a way that the restriction of the function to such a hexagon is simply a shift of its restriction to any of the other hexagons. This in no way contradicts the fact that a doubly periodic meromorphic function has a fundamental region that is a parallelogram: the vertices of such a parallelogram (indeed, in this case a rectangle) may be taken to be the centers of four suitably located hexgaons.

These functions are named after Alfred Cardew Dixon,[1] who introduced them in 1890.[2]

Dixon's elliptic functions are denoted sm and cm, and they satisfy the following identities:

where and is the Beta function
where is Weierstrass's elliptic function
