Abstract:

We consider a bounded domain $\Omega$ in ${{\mathbf {C}}^n}$ and the Banach algebra $A(\Omega )$ of all continuous functions on $\bar \Omega$ which are analytic in $\Omega$. Fix ${f_1}, \ldots ,{f_k}$ in $A(\Omega )$. We say they are a set of generators if $A(\Omega )$ is the smallest closed subalgebra containing the ${f_i}$. We restrict attention to the case when $\Omega$ is strictly pseudoconvex and smoothly bounded and the ${f_i}$ are smooth on $\bar \Omega$. In this case, Theorem 1 below gives conditions assuring that a given set ${f_i}$ is a set of generators.
