Idea

A simplicial weak equivalence is a weak equivalence in the standard homotopy theory of simplicial sets, hence with respect to the classical model structure on simplicial sets.

Definition

A morphism ff between simplicial sets is a simplicial weak equivalence if any of the following equivalent conditions is satisfied (where Ex Ex^\infty denotes Kan fibrant replacement):
