Abstract: We study the best possible energy decay rates for a class of linear second-order dissipative evolution equations in a Hilbert space. The models we consider are generated by a positive selfadjoint operator $ A$ having a bounded inverse. Our discussion applies to important examples such as the classical wave equation, the dynamical wave equation with Wentzell boundary conditions and many others.

Additional Notes: Part of this work was done during the visit of GG and JG to the National Laboratory of Scientific Computation (Brasil) during July 2008. The Goldsteins are most grateful for the gracious hospitality they received from G. Perla Menzala and Carlos Moura.
The third author was partially supported by a Research Grant of CNPq (Proc. 301134/2009-0) and Project Universal (Proc. 47296/2008-3) from the Brazilian Government. The third author would like to express his gratitude for such important support. He is also very thankful to Prof. E. Zuazua. Several years ago he discussed with him the overdamping phenomenon ([13]) and its implications.
