Conformal invariance of the writhe of a knot
R. Langevin, J. O'Hara
We give a new proof of an old theorem by Banchoff and White 1975 that claims that the writhe of a knot is conformally invariant.

Conformally invariant energies of knots II
R. Langevin, J. O'Hara
This paper has been withdrawn by the authors, as it was combined with "Conformally invariant energies of knots I" (math/0409396) to be "Conformally invariant energies of knots" whi…

Conformally invariant energies of knots
R. Langevin, J. O'Hara
Conformally invariant functionals on the space of knots are introduced via extrinsic conformal geometry of the knot and integral geometry on the space of spheres. Our functionals a…
