Compact endomorphisms of H infinity of D
J. F. Feinstein, Herbert Kamowitz
When G is a region in the complex plane, compact composition operators on the uniform algebra of bounded analytic functions on G and the spectra of these operators were described b…
A note on ideal spaces of Banach Algebras
J. F. Feinstein, D. W. B. Somerset
In a previous paper the second author introduced a compact topology on the space of closed ideals of a unital Banach algebra A. If A is separable then this topology is either metri…
Strong regularity for uniform algebras
J. F. Feinstein, D. W. B. Somerset
A survey is given of the work on strong regularity for uniform algebras over the last thirty years, and some new results are proved, including the following. Let A be a uniform alg…
Strong Ditkin algebras without bounded relative units
J. F. Feinstein
In a previous note the author gave an example of a strong Ditkin algebra which does not have bounded relative units in the sense of Dales. In this note we investigate a certain fam…
