چکیده
|
The article studies the concept of a (ϕ, ψ)− biprojective and (ϕ, ψ)−pseudo amenable banach algebra a, where ϕ is a continuous homomorphism on a and ψ ∈ φa. we show if a is (ϕ, ψ)− contractible, then a a is (ϕ, ψ)− biprojective. the converse holds, whenever a is either unital or commutative and there exist a_0 ∈ a such that ϕ (a_0) = a_0
