چکیده
|
In this paper, we introduce a notion of connes biprojectivity for a dual banach algebra a with respect to its w∗-closed ideal i, say i-connes biprojectivity. some lipschitz algebras lipα(x) and some matrix algebras are studied under this new notion. also, with some mild assumptions, the relation between iconnes biprojectivity and left ϕ-contractibility is given, where ϕ is a w∗-continuous multiplicative linear functional on a. as an application, we characterize connes biprojectivity of some lipschitz algebras.
