Differentiable properties of the C 0 semigroup associated with dissipation continuation linear damped elastic system

讨论了二阶线性弹性阻尼系统弹性算子和阻尼算子具“耦合”现象的相应Ｃ０半群的半群性质．

The differentiable properties and exponential decay of the C 0 semigroup associated with coupled phenomenon between the elastic operator and damped operator for second order linear damped elastic system in Hilbert space are discussed.This results can be applied to distribution parameter system described by concrete partial differential equation,conveniently.
