双平坦型巴拿赫代数

Biflat-like Banach algebras

Sanaz Haddad sabzevar, Amin Mahmoodi

摘要:

给定巴拿赫代数$ \mathcal{A} $及其上的连续同态$σ$,引入了$ \mathcal{A} $的$σ$ -双平坦性的概念.这是双平坦性的一个推广,并证明了它们是不同的。研究了$σ$ -双平坦性与其他一些相近的概念如$σ$ -双投射性和$σ$ -顺从性之间的关系。讨论了巴拿赫代数张量积的$σ$ -双平坦性.

英文摘要:

Given a Banach algebra $ \mathcal{A} $ and a continuous homomorphism $σ$ on it, the notion of $σ$-biflatness for $ \mathcal{A} $ is introduced. This is a generalization of biflatness and it is shown that they are distinct. The relations between $σ$-biflatness and some other close concepts such as $σ$-biprojectivity and $σ$-amenability are studied. The $σ$-biflatness of tensor product of Banach algebras are also discussed.
