Topologies on the space of ideals of a Banach algebra

Ferdinand Beckhoff (1995)

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...

What follows is the opening conference of the late night seminar at the III Conference on Banach Spaces held at Jarandilla de la Vera, Cáceres. Maybe the reader should not take everything what follows too seriously: after all, it was designed for a friendly seminar, late in the night, talking about things around a table shared by whisky, preprints and almonds. Maybe the reader should not completely discard it. Be as it may, it seems to me by now that everything arrives in the nick of...
