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.Department of Mathematics, Hokkaido UniversityDepartmental Bulletin Paperapplication/pdfhttp://hdl.handle.net/2115/69358info:doi/10.14943/83754https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/69358/1/pre609.pdfHokkaido University Preprint Series in Mathematics6091322003-10-18engpublisher
