Topologies on the space of ideals of a Banach algebra

Ferdinand Beckhoff (1995)

Studia Mathematica

Similarity:

Some topologies on the space Id(A) of two-sided and closed ideals of a Banach algebra are introduced and investigated. One of the topologies, namely τ , coincides with the so-called strong topology if A is a C*-algebra. We prove that for a separable Banach algebra τ coincides with a weaker topology when restricted to the space Min-Primal(A) of minimal closed primal ideals and that Min-Primal(A) is a Polish space if τ is Hausdorff; this generalizes results from [1] and [5]. All subspaces...
