In the mathematical field of topology, a homeomorphism (from Greek (homoios) 'similar, same', and (morph) 'shape, form', named by Henri Poincaré[1][2]), topological isomorphism, or bicontinuous function is a bijective and continuous function between topological spaces that has a continuous inverse function.A mug and donut are used in the example.A continuous deformation between a coffee mug and a donut (torus) illustrating that they are homeomorphic. But there need not be a continuous deformation for two spaces to be homeomorphic only a continuous mapping with a continuous inverse function. Photo Credit: Wikipedia
Bill Hancock BHancock@CherryRoad.com BALLINGER — Michael Evans is excited about math. Not just math itself, but specifically Category Theory (CT). He’s more than excited. The…
