| Outline of Final Research Achievements |
Study of the operators in function spaces by harmonic analysis is very effective for partial differentiable equations. Moreover, it is important that an operator in some function spaces is bounded. Main subjects in our research are study of Fourier multiplier operators, study of fractional integral operators in Morrey spaces, and study of modulation spaces which are related to partial differential equations. First, we gave a simple proof of the restriction theorem of Fourier multipliers, and generalized the result of the fractional integral operators in Morrey spaces. Also we developed the result in modulation spaces by the study of operating functions.
