c534985d3f move files from Spectral 2018-09-11 19:25:32 +02:00

9a17a244c9 move more results and make arguments explicit 
More results from the Spectral repository are moved to this library
Also make various type-class arguments of truncatedness and equivalences which were hard to synthesize explicit

3d0d0947d6 various cleanup changes in library 
some of the changes are backported from the hott3 library
pi_pathover and pi_pathover' are interchanged (same for variants and for sigma)
various definitions received explicit arguments: pinverse and eq_equiv_homotopy and ***.sigma_char
eq_of_fn_eq_fn is renamed to inj
in definitions about higher loop spaces and homotopy groups, the natural number arguments are now consistently before the type arguments

afdcf7cb71 backport some changes from lean 3 
ap_compose' is reversed, and is_trunc_equiv_closed and variants don't have a type class argument anymore
