Leonardo de Moura	e9809a453d	fix(library/data/finset/equiv): broken proof ... TODO: investigate why the proof has to be fixed	2015-09-11 23:24:29 -07:00
Leonardo de Moura	40ef589d8c	fix(library/data/finset,library/data/list): fixes #799 ... Make sure standard library - theories folder can be compiled with --to_axiom	2015-08-15 09:49:40 -07:00
Jeremy Avigad	4a36f843f7	refactor(library/algebra/group_power,library/*): change definition of pow ... I changed the definition of pow so that a^(succ n) reduces to a * a^n rather than a^n * a. This has the nice effect that on nat and int, where multiplication is defined by recursion on the right, a^1 reduces to a, and a^2 reduces to a * a. The change was a pain in the neck, and in retrospect maybe not worth it, but oh, well.	2015-08-14 18:49:57 -07:00
