Two direct proofs on the analyticity of the S. C. semigroup arising in abstract thermo-elastic equations
The authors provide two abstract direct proofs of the analyticity of the so called contraction semigroups, which arise in thermo-elastic systems under a variety of physical boundary conditions. A fortiori, the semigroups are then uniformly stable. Several examples illustrate the theory.
