Floris van Doorn	9342fe2716	feat(hott) move many lemmas to library, and cleanup various parts	2016-12-02 16:55:23 -08:00
Floris van Doorn	52dd6cf90b	feat(hott): Port files from other repositories to the HoTT library. ... This commit adds truncated 2-quotients, groupoid quotients, Eilenberg MacLane spaces, chain complexes, the long exact sequence of homotopy groups, the Freudenthal Suspension Theorem, Whitehead's principle, and the computation of homotopy groups of almost all spheres which are known in HoTT.	2016-05-06 14:27:27 -07:00
Floris van Doorn	8db4676c46	feat(hott): various changes and additions in the HoTT library ... Add more theorems about mapping cylinders, fibers, truncated 2-quotient, truncated univalence, pre/postcomposition with an iso in a precategory. renamings: equiv.refl -> equiv.rfl and equiv_eq <-> equiv_eq'	2016-05-06 14:27:27 -07:00
Floris van Doorn	5cacebcf86	feat(hott): replace assert by have and merge namespace equiv.ops into equiv ... The coercion A ≃ B -> (A -> B) is now in namespace equiv. The notation ⁻¹ for symmetry of equivalences is not supported anymore. Use ⁻¹ᵉ	2016-03-03 10:13:21 -08:00
Floris van Doorn	087c44d614	style(hott): rename instances of pType using pfoo instead of Foo ... For example, the pointed suspension operation was called Susp before this commit, but now is called psusp	2016-02-22 11:15:38 -08:00
