Abstract

The paper deals with the definition and computation of the writhingnumber of an arbitrary fragment of a space curve. The approach is basedon closing the tangent indicatrix with a geodesic. A relationship connectingthe writhe with the Gau? integral over the open curve is studied.Single and double helical shapes are presented as examples.
