Abstract:

In this paper we will characterize the weak-star closed algebra $\mathcal {A}$ generated by the canonical model associated with a generalized Bergman kernel defined on a domain $G$ in the plane, whose spectrum is a spectral set. In fact, $\mathcal {A}$ equals the space ${H^\infty }\left ( {{G_0}} \right )$ of all bounded analytic functions on an appropriate set ${G_0}$ containing $G$.
