چکیده
|
Let a be a non-zero normed vector space and let ϕ be a non-zero element of a∗ such that ||ϕ|| ≤ 1. assume that k = b(0) is the closed unit ball of a. according to the our recent studies on the spaces of (cbϕ(k), || · ||∞) and (cbϕ(k), || · ||ϕ), generated by cb(k) and equipped with a new product “ · ” and different norms||·||∞ and ||·||ϕ, the n−weak amenability of (cbϕ(k), ||·||∞) and (cbϕ(k), || · ||ϕ) are investigated.
