弱乘子双代数

Weak multiplier bialgebras

Gabriella Böhm, José Gómez-Torrecillas, Esperanza López-Centella

摘要:

利用乘子值余乘给出了弱双代数的一个非酉推广。某些典型的子代数的乘子代数(命名为'基代数')进行co-separable的共同Frobenius coalgebra结构。证明了弱乘子双代数上的适当模通过基代数上的(余)模张量积构成一个幺半范畴。讨论了与Van Daele和Wang的弱乘子霍普夫代数的关系.

英文摘要:

A non-unital generalization of weak bialgebra is proposed with a multiplier-valued comultiplication. Certain canonical subalgebras of the multiplier algebra (named the `base algebras') are shown to carry coseparable co-Frobenius coalgebra structures. Appropriate modules over a weak multiplier bialgebra are shown to constitute a monoidal category via the (co)module tensor product over the base algebra. The relation to Van Daele and Wang's (regular and arbitrary) weak multiplier Hopf algebra is discussed.
