About the contractibility of the walking coinductive equivalence

Viktoriya Ozornova, Martina Rovelli, Tashi Walde

We study the marked simplicial set obtained as the Roberts-Street nerve of the walking coinductive equivalence. We show that it is a non-contractible saturated complicial set for w…

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…

A model for the coherent walking -equivalence

Amar Hadzihasanovic, Félix Loubaton, Viktoriya Ozornova +1

We prove that a certain -category, which was constructed in previous work by the third and fourth author, is a model for the fully coherent walking -equivalence. Further, app…

What is an equivalence in a higher category?

Viktoriya Ozornova, Martina Rovelli

The purpose of this survey is to present in a uniform way the notion of equivalence between strict -categories or -categories, and inside a strict -category o…
