On the Radius of Analyticity for a Korteweg-de Vries-Kawahara Equation with a Weakly Damping Term

Aissa Boukarou, Daniel Oliveira da Silva

We consider the Cauchy problem for an equation of Korteweg-de Vries-Kawahara type with initial data in the analytic Gevrey spaces. By using linear, bilinear and trilinear estimates…
