Bresse Beam with Damping and Logarithmic Source
摘要
This paper investigates the stabilization of a Bresse system with internal damping and logarithmic source. The authors use the potential well theory. For initial data in the stability set created by the Nehari surface, the existence of a global solution is proved by using Faedo-Galerkin’s approximation. The Nakao theorem gives the exponential decay. A numerical approach is presented to illustrate the results obtained.
