LOCAL SOLVABILITY OF A CONSTRAINED GRADIENT SYSTEM OF TOTAL VARIATION
Preprint Series # 609
This is the latest version of this item.
A 1-harmonic map flow equation, a gradient system of total variation where values of unknowns are constrained in a compact manifold in R^N is formulated by use of subd-ifferentials of a singular energy - the total variation. An abstract convergence result is established to show that solutions of approximate problem converge to a solution of the limit problem. As an application of our convergence result a local-in-time solution of 1-harmonic map flow equation is constructed as a limit of the solutions of p-harmonic (p > 1) map flow equation, when the initial data is smooth with small total variation under periodic boundary condition.
