    Winding Number & Linking Number
    Articles, Studies and Background Information



      A winding number represents the total number of times that a curve travels around a point. The winding number is positive if the curve travales around the point counterclockwise and negative if the curve travels clockwise.

      Winding No. +2

      Winding No. -2

      A linking number represents the number of times that two curves wind one around the other. The linking number may be positive or negative depending on the winding orientation of the two curves regarding each other.

      Linking No. +1

      Linking No. -1
