WebMade available by U.S. Department of Energy Office of Scientific and Technical Information ... WebAn expression for the writhe as a function of arclength for an arbitrary space curve is obtained. The formula is built on the base of closing the tangent indicatrix with a geodesic. The cor- responding closure of a curve in 3-space is explicitly constructed. The addition rule for writhe is formulated.
