Iterated traces in 2-categories and Lefschetz theorems
arXiv:1908.07497 · doi:10.2140/agt.2022.22.815
Abstract
While not obvious from its initial motivation in linear algebra, there are many context where iterated traces can be defined. In this paper we prove a very general theorem about iterated 2-categorical traces. We show that many Lefschetz-type theorems in the literature are consequences of this result and the new perspective we provide allows for immediate spectral generalizations.
