We define a category parameterizing Calabi–Yau algebra objects in an infinity category of spans. Using this category, we prove that there are equivalences of infinity categories relating, firstly: 2-Segal simplicial objects in C to algebra objects in Span(C); and secondly: 2-Segal cyclic objects in C to Calabi–Yau algebra objects in Span(C).

跨度中的2-Segal对象和代数

我们定义一个类别,该类别在跨度的无限类别中参数化Calabi–Yau代数对象。使用这一类别,我们证明了存在无穷类别的等价关系,首先,它们与:C中的2-单义简单对象与Span(C)中的代数对象有关;其次:C中的2个半脉冲循环对象到Span(C)中的Calabi–Yau代数对象。
