Computads with invertible generators for weak Ï-categories
Thibaut Benjamin, Camil Champin, Ioannis Markakis
We extend the notion of computads for weak \(Ï\)-categories to allow marking certain generators as invertible, and describe inductively the free \(Ï\)-categories they generate. T…

A type theory for invertibility in weak -categories
Thibaut Benjamin, Camil Champin, Ioannis Markakis
We present a conservative extension ICaTT of the dependent type theory CaTT for weak -categories with a type witnessing coinductive invertibility of cells. This extension allow…
