| Research Abstract |
First of all, by this project important applications of methods of functional analysis to nonlinear problems have been studied and promoted. Among various results thus obtained, the following deserves a particular mention; Analytical and numerical analysis of a free boundary problem arising from a mathematical study of fluid motion arround planets. Nonlinear eigenvalue problems and related bifurcation problems for <DELTA> u + <lambda> <e^u> = 0. Blowing-up problems of solutions of quasi-linear parabolic equations. Actually, these results are important by their own right but are extremely interesting because of profound combination of functional analysis with numerical analysis and function theoretic/differential geometric methods. Furthermore, some remarkable results have been obtained in connection with partial differential equations by means of a very stochastic method, i.e. the Mariavan calculus. Finally, a considerable progress in the study of spectral inverse problems has been made by this project.
