Outline of Final Research Achievements

We studied the relations between various properties of solutions to linear dispersive equations and geometry of symbols of the equations. We considered the Cauchy problem for dispersive evolution equations with variable coefficients, which might be unbounded, of order greater than or equal to two on the Euclidean space, and obtained necessary conditions and sufficient conditions for the Cauchy problem to be well-posed. We also obtained new results on growth order of solutions to wave equations with time-dependent, spatially compact metric perturbations.
