摘要: Earlier obtained numerical and analytical (non-path-integral) results for the writhe of a circular polymer are reproduced exactly employing available path integral models semiflexible chains. It is confirmed analytically that average scales with root chain length. We also briefly discuss related topological problems (e.g. knotting polymers), which could be formulated solved use integrals.
