I can relate the first and fourth, and the second and third.
Two uses of the word infinity occur in Cantor's theories of infinity: there are infinite ordinals and infinite cardinals.
"Every Möbius transformation is a bijective conformal map of the Riemann sphere to itself. Indeed, every such map is by necessity a Möbius transformation." so says http://en.wikipedia.org/wiki/Moebius_transformation (wherein you may find links to articles on the various technical terms.)
