Research Abstract

For the construction of Morse (variational) flows, we introduced the Discrete Morse Flows method, which has been adopted and named Minimizing Movements method by De Giorgi. This approach has some merits in construction of Morse flows, since we can make the most of minimizers to a series of variational functionals inductively introduced starting with initial data. By using this method, we construct Morse flows to variational problems of harmonic map type, in the treatment of which we have noticed the method is available under the weaker assumptions on initial and boundary data. We are trying to approach the construction problems of Morse flows to harmonic map variational problems between metric manifolds, which have no smoothness of the coefficients of the second order differential operators. In the analysis of Discrete Morse Flows, we carry out local estimates of time-discrete partial differential equations of elliptic-parabolic type, so that we have achieved De Giorgi-Nash type Holder estimates and Campanato estimates, and the higher integrability to the gradients of Gehring type. Such kinds of estimates are proved to hold independently of the approximation schemes, which enables to construct Morse flows through Discrete Morse Flows. In conclusion of a series of these research work, we have recognized the characteristics of Discrete Morse Flows method that it can be made use of to the construction problems of Morse flows, to which Leray-Schauder with Schauder estimates cannot be directly applied.
