Abstract

This paper deals with the behavior at infinity of solutions to a class of wave equations with nonlinear damping
terms defined in a semi-infinite cylinder. The spatial behavior of solutions is studied and an alternative of
Phragmén-Lindelöf type theorems is obtained in the results. The main point in the contribution is the use of energy method.
