| Aug 15, 2017 at 20:00 | comment | added | user290425 | @MichaelRenardy . This isn't an exercise problem. I am working though the paper "Spectrum-preserving linear mappings between Banach algebra and Jordan-Banach algebras" (academic.oup.com/jlms/article-abstract/62/3/917/874307/…) by Aupetit. In his proof of Theorem 1.1 (ii) he defines these two (and two other) mappings and then states that $p_0a= a_0$. I am trying to see why this is true, but in order to do so, I needed the result in my question. | |
