Abstract
Let be an additive semigroup with , be an admissible weight on , be a unital Banach algebra, and let for be a generalized Dirichlet series satisfying where for all . We take to be a commutative complex Banach algebra (with ) and - the Banach algebra of matrices having entries from , where is either the complex plane or the real algebra of bicomplex numbers or quaternions, and show that is invertible if and only if the closure of the image of is contained in the set of all invertible elements of .
