An -groupoid is an ∞-category (see there for more details) in which all k-morphisms for all are equivalences.
This is also called an ∞-groupoid. In the literature the term “-groupoid” is usually reserved for algebraic models instead of geometric models.
How strict the -category and the inverses must be can vary. Somes authors that use the term ‘-groupoid’ mean strict ∞-groupoid by default and speak of weak -groupoid otherwise.
