The Local de Branges-Rovnyak Construction and Complete Nevanlinna-Pick Kernelsnted. This construction generalizes versions of the de Branges-Rovnyak construction used by a number of authors, including Agler and Muller for weighted shifts (diagonal kernels) satisfying various polynomial identities.

On Banach Algebras Generated by Two Idempotentsal algebras, the Gel’fand map realizes an imbedding into the algebra of all continuous functions on a well-defined set, namely the space of maximal ideals. Analogously, a semisimple algebra can be shown to be isomorphic to a subalgebra of all continuous 2 x 2 matrix-valued functions on a compact set
