We study subalgebras of equipped with topologies that generalize both the uniform and the strict topology. In particular, we study the Stone-Weierstrass property and describe the ideal structure of these algebras.
We develop the theory of Segal algebras of commutative C*-algebras, with an emphasis on the functional representation. Our main results extend the Gelfand-Naimark Theorem. As an application, we describe faithful principal ideals of C*-algebras. A key ingredient in our approach is the use of Nachbin algebras to generalize the Gelfand representation theory.
Let X be a completely regular Hausdorff space, a cover of X, and the algebra of all -valued continuous functions on X which are bounded on every . A description of quotient algebras of is given with respect to the topologies of uniform and strict convergence on the elements of .
