一般而言,满射有界同态不能保持$n$-弱顺从性。然而,我们证明了如果所涉及的同态具有右逆,则它保持该性质。我们对几个Banach代数上的某些同态检验了这一事实。
A surjective bounded homomorphism fails to preserve $n$-weak amenability, in general. We however show that it preserves the property if the involved homomorphism enjoys a right inverse. We examine this fact for certain homomorphisms on several Banach algebras.
