Idea

An ω\omega-groupoid is an ∞-category (see there for more details) in which all k-morphisms for all kk \in \mathbb{N} are equivalences.

This is also called an ∞-groupoid. In the literature the term “ω\omega-groupoid” is usually reserved for algebraic models instead of geometric models.

How strict the ω\omega-category and the inverses must be can vary. Somes authors that use the term ‘ω\omega-groupoid’ mean strict ∞-groupoid by default and speak of weak ω\omega-groupoid otherwise.
