Abstract
A uniform algebra A on a compact space X is tight if for each gϵC(X), the Hankel-type operator f → gf + A from View the MathML source is weakly compact. Two families of uniform algebras are shown to be tight: the algebras such as R(K) that arise in the theory of rational approximation on compact subsets of the complex plane, and algebras of analytic functions on domains in View the MathML sourcen for which a certain View the MathML source-problem is solvable. A couple of characterizations of tight algebras are given, and one of these is used to show that the property of being tight places severe restrictions on the Gleason parts of A and the measures in A⊥.
