New Lower Bounds of Spatial Analyticity Radius for the Kawahara Equation
In this paper, an algebraic decay rate for the radius of spatial analyticity of solutions to the Kawahara equation ∂tu+β∂x5u+α∂x3u+u∂xu=0,β≠0 is investigated. With given analytic initial data having a fixed radius of analyticity σ0, we derive an algebraic decay rate σt∼t−1/2 for the uniform radius o...
