Boa postura da "boa" equação de Boussinesq em espaços de Sobolev na reta e no toro

Abstract

In this work we address the problem of good posture of the nonlinear partial differential equation known as the "good" Boussinesq equation in Sobolev spaces. We will present the results of good posture in both cases, the periodical, when the initial data and the solutions are periodic in the spatial variable, and the non-periodic one.
