摘要: In the present paper we investigate linear elastic systems with damping ÿ+Bẏ+Ay=0 in Hilbert spaces, where A and B are unbounded positive definite linear operators. We have obtained the most fundamental results for the holomorphic property and exponential stability of the semi-groups associated with these systems via inclusion relation of the domains of A and B.
