✦ Synopsis

An equation which describes the flow of energy in energy conservative semi-and full discretizations of hyperbolic equation4 is derived. While Ihe form of this equation for semi-discretizations verfies known principles of group velocity and wave propagarion in periodic struclures. its form and strict applicability to discrete-space-discrete-time systems such as those resulring from Ihe full discretizakn of hyperbolic equations are new results.

We prove the following results: 1. A unique smooth solution exists for a short time for the heat equation associated with the Möbius energy of loops in a euclidean space, starting with any simple smooth loop. 2. A critical loop of the energy is smooth if it has cube-integrable curvature. Combining
