可分Frobenius Monoidal函子保持什么

What Separable Frobenius Monoidal Functors Preserve

Micah Blake McCurdy, Ross Street

摘要:

可分离的弗罗贝纽斯么半群函子由Szlachanyi和Day和Pastro定义和研究,并由Cockett和Seely在更一般的上下文中定义和研究。我们在这里的目的是在一个非常精确的意义上发展他们的理论。我们确定了它们在幺半范畴范畴中保持什么样的方程。例如,我们证明他们保持宽松(意味着不一定可逆)杨巴克斯特算子,弱杨巴克斯特算子的意义上的阿隆索阿尔瓦雷斯等,和(在辫状的情况下)在帕斯特罗和街道的意义上的弱双音节。事实上,我们刻画了哪些monoidal表达式被保留(或者更确切地说,在定义明确的意义上,在共轭下是稳定的)。证明了每个弱Yang-Baxter算子都是真Yang-Baxter算子在可分Frobenius monoidal函子下的象。Prebimonoidal函子也定义和讨论。

英文摘要:

Separable Frobenius monoidal functors were defined and studied under that name by Szlachanyi and by Day and Pastro, and in a more general context by Cockett and Seely. Our purpose here is to develop their theory in a very precise sense. We determine what kinds of equations in monoidal categories they preserve. For example we show they preserve lax (meaning not necessarily invertible) Yang-Baxter operators, weak Yang-Baxter operators in the sense of Alonso Alvarez et al., and (in the braided case) weak bimonoids in the sense of Pastro and Street. In fact, we characterize which monoidal expressions are preserved (or rather, are stable under conjugation in a well-defined sense). We show that every weak Yang-Baxter operator is the image of a genuine Yang-Baxter operator under a separable Frobenius monoidal functor. Prebimonoidal functors are also defined and discussed.
