| Research Abstract |
Study in harmonic analysis is important for partial differential equations. Especially, study of singular integral operators and fractional integral operators are useful for differential equations, and we study the boundedness of those operators in some function spaces. In this plan, we got the boundedness of multilinear fractional integral operators in weighted Morrey spaces, which are gereralization whose results were already known and those results are accepted in the journal. Also we obtained some properties of Fourier multipliers and the predual in Morrey spaces, and those resuklts are accepted in the two journals.
