M-ideal structure in Banach algebras Academic Article uri icon


  • It is shown that M-ideals in a Banach algebra with identity are subalgebras, and that they are ideals if the algebra is commutative. Counterexamples demonstrate that these are the strongest results available. The theory is then applied to familiar classes of Banach spaces. © 1978.
