Winding Number (Contour)
Denoted 
and defined as the number of times a path 
curve passes around a point.
The contour winding number was part of the inspiration for the idea of the Degree of a Mapbetween two Compact, oriented Manifolds of the same Dimension. Inthe language of the Degree of a Map, if 
is a closed curve(i.e., 
), then it can be considered as a Function from 
to 
. Inthat context, the winding number of around a point 
in is given by the degree of the Map
from the Circle to the Circle.
