ABSTRACT
Let be a Hopf brace. We first show that the category of left compatible modules over is a tensor category. Next, we show that its Drinfeld centre is equivalent to the category of left Yetter–Drinfeld modules over as a braided tensor category. Finally, we show that Radford's biproduct and constitute a Hopf brace, where R is a Hopf algebra in . This presents some new method to construct Hopf braces.

从 Hopf 大括号构建编织张量类别
摘要
让做一个 Hopf 支架。我们首先表明左兼容模块的类别超过是张量范畴。接下来,我们证明它的 Drinfeld 中心等价于类别左侧的 Yetter-Drinfeld 模块作为编织张量类别。最后,我们证明了 Radford 的二乘和构成一个 Hopf 大括号,其中R是一个 Hopf 代数. 这提出了一些构建 Hopf 大括号的新方法。
