  Conformal geometry

  In mathematics, conformal geometry is the study of the set of angle-preserving (conformal) transformations on a space. In two real dimensions, conformal geometry is precisely the geometry of Riemann surfaces. In more than two dimensions, conformal geometry may refer either to the study of conformal...

  Conformal map

  In mathematics, a conformal map is a function which preserves angles. In the most common case the function is between domains in the complex plane. More formally, a map, is called conformal (or angle-preserving) at if it preserves oriented angles between curves through with respect to their...
