内容摘要：We introduce a new characterization of exponential stability over Banach spaces using the essential type of a semigroup. This new characterization allows us to find new results on stabilization and the lack of exponential stabilization. We show some methods to calculate or estimate the essential type. We show applications for wave equations and Timoshenko systems.
