Costa's minimal surface
From Wikipedia, the free encyclopedia
In topology, Costa's minimal surface is an embedded minimal surface and was discovered in 1982 by the Brazilian mathematician Celso Costa. It is also a surface of finite topology, which means that it has no boundaries and does not intersect itself. Its topology is a three punctured torus.
Until its discovery, only the plane, helicoid and the catenoid were believed to be embedded surfaces that could be formed by puncturing a compact surface. The Costa surface evolves from a torus, which is deformed until the planar end becomes catenoidal. Defining these surfaces on rectangular tori of arbitary dimensions yields the Costa surface. Its discovery triggered research and discovery into several new surfaces and open conjectures in topology.
The Costa surface can be described using the Weierstrass zeta and the Weierstrass elliptic functions.
