| Research Abstract |
By developing a global boundedness theory of Fourier integral operators, we established a method to deduce estimates for solutions to partial differential equations from those for their normal forms, and furthermore, prepared a new method to make a comparison of estimates for solutions from the comparison of symbols of two partial differential equations, so that we approached to nonlinear problems.
