The -category of spans
Jonte Gödicke, Quoc P. Ho, Walker H. Stern
In this paper, we construct the -category of spans, also known as correspondences, in any given -category $\mathcal…
Cyclic Segal Spaces
Julia E. Bergner, Walker H. Stern
In this survey article, we review some conceptual approaches to the cyclic category , as well as its description as a crossed simplicial group. We then give a new proof of the m…
Frobenius and commutative pseudomonoids in the bicategory of spans
Ivan Contreras, Rajan Amit Mehta, Walker H. Stern
In previous work by the first two authors, Frobenius and commutative algebra objects in the category of spans of sets were characterized in terms of simplicial sets satisfying cert…
On cofinal functors of -bicategories
Fernando Abellán, Walker H. Stern
In this work, we study the notion of cofinal functor of -bicategories with respect to the theory of partially lax colimits. The main result of this paper is a characterizat…
2-Cartesian fibrations II: A Grothendieck construction for -bicategories
Fernando Abellán, Walker H. Stern
In this work, we conclude our study of fibred -bicategories by providing a Grothendieck construction in this setting. Given a scaled simplicial set (which need not be f…
2-Cartesian fibrations I: A model for -bicategories fibred in -bicategories
Fernando Abellán García, Walker H. Stern
In this paper, we provide a notion of -bicategories fibred in -bicategories which we call 2-Cartesian fibrations. Our definition is formulated using the language of…
