On propagation of regularities and evolution of radius of analyticity in the solution of the fifth order KdV-BBM model
Xavier Carvajal, Mahendra Panthee
We consider the initial value problem (IVP) associated to a fifth order KdV-BBM type model that describes the propagation of unidirectional water waves. We prove that the regularit…

Sharp well-posedness for a coupled system of mKdV type equations
Xavier Carvajal, Liliana Esquivel, Raphael Santos
We consider the initial value problem associated to a system consisting modified Korteweg-de Vries type equations $$ \partial_tv + \partial_x^3v + \partial_x(vw^2) =0,\ \ v(x,0)=ϕ(…
