Isabelle-HoTT - trying to make Isabelle/HoTT work with Isabelle 2021-1

	Commit message (Collapse)	Author	Files	Lines
2018-07-09	Pre-universe implementation commit	Josh Chen	1	-1/+1

2018-07-07	Library snapshot. Methods written, everything nicely organized.	Josh Chen	1	-1/+0

2018-07-03	Refactor HoTT_Methods.thy, proved more stuff with new methods.	Josh Chen	1	-4/+13

2018-06-27	Library organization and formatting	Josh Chen	1	-6/+7

2018-06-12	Type rules now have \"all\" premises explicitly stated, matching the ↵	Josh Chen	1	-0/+15
	formulation in the HoTT book.
2018-06-09	Reorganize code	Josh Chen	1	-248/+0

2018-06-07	Symmetry and transitivity done.	Josh Chen	1	-3/+26

2018-06-07	But also looser than Pair	Josh Chen	1	-1/+1

2018-06-07	Nondependent function arrow should bind tighter than the Pi former, but ↵	Josh Chen	1	-21/+43
	looser than equality.
2018-06-05	Code formatting	Josh Chen	1	-41/+54

2018-06-05	Proved that the inductor on Sum has the correct type.	Josh Chen	1	-17/+31

2018-06-05	Dependent sum done, I think.	Josh Chen	1	-28/+40

2018-06-04	Prod_comp should have a type constraint. This also fixes a false proof for ↵	Josh Chen	1	-22/+31
	the dependent sum projection functions.
2018-06-01	Should be final version of Prod. Theorems proving stuff about currying. ↵	Josh Chen	1	-22/+15
	Rules for Sum, going to change them to use object-level arguments more.
2018-05-30	New type rules for dependent product and sum.	Josh Chen	1	-12/+29

2018-05-30	Fixed dependent product rules, hopefully final now.	Josh Chen	1	-3/+2

2018-05-29	More rigorous rules for Product type. Propositions and proofs all working, ↵	Josh Chen	1	-12/+17
	but have to think about maybe relaxing the computation rule, or else automating the currying of dependent functions.
2018-05-28	Dependent product rules done and proofs of typing properties so far work. ↵	Josh Chen	1	-27/+54
	Starting on dependent sums.
2018-05-23	pre-system upgrade commit	Josh Chen	1	-35/+40

2018-05-14	Added precedences. Need to figure out how to organize metatypes.	Josh Chen	1	-13/+12

2018-05-10	Decided to go with no explicit type declarations in object-lambda ↵	Josh Chen	1	-14/+25
	expressions. Everything in the proof stuff is working at the moment.
