Invertibility preserving maps preserve idempotents.

open access: yesMichigan Mathematical Journal, 1998
Let \({\mathcal B}\) be a unital norm-closed operator algebra on some complex Banach space such that \({\mathcal B}\) contains all of the finite-rank operators. The main result of the paper under review is that, if \({\mathcal A}\) is a unital Banach algebra and \(\varphi:{\mathcal A}\to{\mathcal B}\) is a unital surjective linear mapping which takes ...
