Improved blow-up of solutions of a generalized Boussinesq equation
Computational & Applied Mathematics. Springer Heidelberg, v. 18, n. 3, n. 333, n. 341, 1999.
In this work we consider the blow-up of solutions of the Cauchy problem for a generalized Boussinesq equation. Our main result shows that for initial data satisfying certain hypotheses, the corresponding solution blows-up in H-1-norm. Our proof relies on the method of concentration-compactness combined with general methods for studying the blow-up of hyperbolic nonlinear equations.183333341
