Existence of strong solutions and global attractors for the suspension bridge equations. (English) Zbl 1125.34019

The authors treat a nonlinear ordinary second-order differential equation by establishing some a priori bounds and then proving the convergence of the Faedo-Galerkin approximation method.
Unfortunately, the equation does not describe the deflection of a suspension bridge, whose equation is completely different. In addition, the language is poor and full of mistakes, and the references ignore the huge, classical, literature of the problem.
