Enhanced twisted arrow categories
Fernando Abellán García, Walker H. Stern
Given an -bicategory with underlying -category , we construct a Cartesian fibration $\operatorname{Tw}(\mathbb{D})\to \mathcal{D} \times \…
Theorem A for marked 2-categories
Fernando Abellán García, Walker H. Stern
In this work, we prove a generalization of Quillen's Theorem A to 2-categories equipped with a special set of morphisms which we think of as weak equivalences, providing sufficient…
2-Segal objects and algebras in spans
Walker H. Stern
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 re…
Structured Topological Field Theories via Crossed Simplicial Groups
Walker H. Stern
We show how the framework of crossed simplicial groups may be used to provide a classification of topological field theories on open cobordism categories defined by reductions of t…
