Abstract: In this article we fully describe the domain of the infinitesimal generator of the optimal state semigroup which arises in the theory of the linear-quadratic problem for a specific class of boundary control systems. This represents an improvement over earlier work of the authors, joint with Lasiecka, where a set inclusion was established, but not an equality. The key part of the proof of this result developes through appropriate asymptotic estimates that take advantage of the regularity analysis previously performed in the study of the optimization problem, while the powers of positive operators, interpolation and semigroups provide the analytical tools. We also attest to the validity of an assumed relation between two significant parameters in the case of distinct systems of coupled hyperbolic-parabolic partial differential equations which are pertinent to the underlying framework.
