Let \(A\) be a Banach algebra and let \(I\) be a closed two-sided ideal in \(A\). \(A\) is \(I\)-weakly amenable if \(H^1(A,I^*) = \{0\}\). Further, \(A\) is ideally amenable if \(A\) is \(I\)-weakly amenable for every closed two-sided ideal \(I\) in \(A\). In this paper we introduce \(\sigma\)-ideal amenability for a Banach algebra \(A\), where \(\sigma\) is an idempotent bounded endomorphism of \(A\).
