Università di Perugia, ItaliaEnriched orthogonality
We consider enriched orthogonality for classes of spaces, with respect to groupoids, simplicial sets and spaces themselves, obtaining characterizations for homotopy equivalences, shape and strong shape equivalences. An example in which homotopy orthogonality implies enriched orthogonality is discussed.* This is a joint work with Marek Golasiński.
