-Limits I: Definition and first consistency results

Lyne Moser, Nima Rasekh, Martina Rovelli

We give a model-independent definition of limits for diagrams valued in an -category. We show that this definition is compatible with the existing notion of homotopy 2-…

Cores and localizations of -categories

Viktoriya Ozornova, Martina Rovelli, Tashi Walde

We consider -categories in the limit via the core or localization functors that forget or invert higher non-invertible arrows, respectively. We compare th…

Zigzags and free adjunctions

Lorenzo Riva, Martina Rovelli

We construct an explicit combinatorial model of the functor which adds right adjoints to the morphisms of an -category, and we speculate on possible extensions to higher di…

The Morita -category of a monoidal category as a -complicial set

Arghan Dutta, Stefano Luneia, Martina Rovelli +1

We provide an explicit and elementary construction of the Morita -category of a monoidal category which satisfies minimal conditions. We construct it as a -coskeleta…

-categories in context

Viktoriya Ozornova, Martina Rovelli

This note is a contribution written for the second volume of the Encyclopedia of mathematical physics. We give an informal introduction to the notions of an -category a…

The -construction as an equivalence between 2-Segal spaces and stable augmented double Segal spaces

Martina Rovelli

This note is a contribution for a proceedings volume of the workshop "Higher Segal Spaces and their Applications to Algebraic K-Theory, Hall Algebras, and Combinatorics". The conte…
