2019-02-17Method "quantify" converts product inhabitation into Pure universal ↵Josh Chen1-2/+2
statements. Also misc. cleanups.
2019-02-11Organize this commit as a backup of the work on type inference done so far; ↵Josh Chen1-22/+24
learnt that I probably need to take a different approach. In particular, should first make the constants completely monomorphic, and then work on full proper type inference, rather than the heuristic approach taken here.

2018-07-11Universes implemented. Type rules modified accordingly. No more automatic ↵Josh Chen1-8/+18

2018-07-07Library snapshot. Methods written, everything nicely organized.Josh Chen1-3/+32
2018-07-03Refactor HoTT_Methods.thy, proved more stuff with new methods.Josh Chen1-74/+30
2018-07-03Rewrote methods: wellformed now two lines, uses named theorems. New, more ↵Josh Chen1-27/+6
powerful derive method. Used these to rewrite proofs.

2018-06-18Dependent projection properties done.Josh Chen1-27/+58
2018-06-18Fixed wrong definition of snd_dep. Proved projection property of snd_dep. ↵Josh Chen1-16/+81
Added type formation rules expressing necessity of the conditions.
2018-06-18Removed all [simp] attributes, these will be added later when I set up the ↵Josh Chen1-18/+31
simplifier. Proved simplification rule for dependent fst.
2018-06-17Proof of projection functions now harder. Should look up automation methods.Josh Chen1-8/+14
