AI总结:

本文基于绳结理论,定义了非半单有限单模绳结张量范畴的(3+1)维拓扑量子场论,提出'色非退化'条件,并推广了Crane-Yetter-Kauffman和Lyubashenko等不变量。

摘要:

我们定义了基于可能非半单有限单模绳结张量范畴的(3+1)维拓扑量子场论,利用绳结理论。这为cobordism假设预测的TQFT提供了显式实现,基于最近的可双射性结果。态空间由可接受的绳结模给出,我们规定了处理柄附加的TQFT。我们给出了一些关于输入范畴的显式代数条件,即为'色非退化'。作为副产品,我们获得了一个带有边界绳结图的4流形不变量,在'扭非退化'情况下,获得了一个3流形不变量。本文的构造推广了半单情况下的Crane-Yetter-Kauffman TQFTs,以及Lyubashenko(因此也包括Hennings和WRT)的3流形不变量。整个构造非常基础,我们可以轻松地 characterize TQFTs的可逆性,研究其在连通和中的行为,并提供了一些例子。

英文摘要:

We define a (3+1)-TQFT associated with possibly non-semisimple finite unimodular ribbon tensor categories using skein theory. This gives an explicit realization of a TQFT predicted by the cobordism hypothesis, based on recent results on dualizability. State spaces are given by admissible skein modules, and we prescribe the TQFT on handle attachments. We give some explicit algebraic conditions on the input category to define this TQFT, namely to be ''chromatic non-degenerate''. As a by-product, we obtain an invariant of 4-manifolds equipped with a ribbon graph in their boundary, and in the ''twist non-degenerate'' case, an invariant of 3-manifolds. Our construction generalizes the Crane-Yetter-Kauffman TQFTs in the semi-simple case, and the Lyubashenko (hence also Hennings and WRT) invariants of 3-manifolds. The whole construction is very elementary, and we can easily characterize the invertibility of the TQFTs, study their behavior under connected sums and provide some examples.
