Hom $\omega$-categories of a computad are free

Abstract

We provide a new description of the hom functor on weak $\omega$-categories, and we show that it admits a left adjoint that we call the suspension functor. We then show that the hom functor preserves the property of being free on a computad, in contrast to the hom functor for strict $\omega$-categories. Using the same technique, we define the opposite of an $\omega$-category with respect to a set of dimensions, and we show that this construction also preserves the property of being free on a computad. Finally, we show that the constructions of opposites and homs commute.

45 pages, updated to change the structure of the paper, add the suspension of $\omega$-categories, change the title and abstract accordingly, add citations and correct a few typos
