Projective ideals of Banach algebras and approximative units
L. I. Pugach Bryansk Institute of Transport Engineering
Abstract:
It is shown that if an ideal of a commutative Banach algebra has a Schauder base, then it is projective iff it contains an approximative unit with some special properties. For uniform algebras a criterion is formulated in terms of peak sets.
