Minapoor, A. Bodaghi and D. Ebrahimi Bagha. They studied weak∗continuous derivations from dual Banach algebras into their weak∗-closed two- sided ideals. This work considers weak∗-continuous derivations of dual triangular Banach algebras into their weak∗-closed two- sided ideals . We investigate when weak∗continuous derivations from these algebras into their weak∗-closed ideals are inner? https://ansne.du.ac.ir/article_156_7b4d26b257ddde60c648c798423acecd.pdf
