内容摘要:In this lecture, we will show some sufficient conditions to a family of semigroups to be exponentially stable, that is, we will show when a semigroup is or not is exponential stable. The difference with other characterizations like Gearhart-Prüss-Sheng Theorem is that instead of using the limitation of the resolvent operator we consider some properties of the essential spectral radius. Finally, we show some applications to elasticity and thermoelasticity.
