G-Space
A 
-space is a special type of Hausdorff Space. Consider a point 
and a Homeomorphism of an openNeighborhood 
of onto an Open Set of 
. Then a space is a -space if, for any two suchNeighborhoods 
and 
, the images of 
under the differentHomeomorphisms are Isometric. If 
, theHomeomorphisms need only be conformal (but not necessarily orientation-preserving).
