Asymptotic Estimates For Some Dispersive Equations On The Alpha-Modulation Space, Justin Trulen
Asymptotic Estimates For Some Dispersive Equations On The Alpha-Modulation Space, Justin Trulen
Theses and Dissertations
The alpha-modulation space is a function space developed by Grobner in 1992. The alpha-modulation space is a generalization of the modulation space and Besov space. In this thesis we obtain asymptotic estimates for the Cauchy Problem for dispersive equation, a generalized half Klein-Gordon, and the Klein-Gordon equations. The wave equations will also be considered in this thesis too. These estimates were found by using standard tools from harmonic analysis. Then we use these estimates with a multiplication algebra property of the alpha-modulation space to prove that there are unique solutions locally in time for a nonlinear version of these partial …
