| Jan 21, 2021 at 23:10 | comment | added | Denis Nardin | Maybe I should add that I do not know any definition of higher Witt groups that do not pass through some version of chain complexes, especially when 2 is not invertible (otherwise you can cheat via periodicity and use simple formulas in low degrees via formations, which are basically length one chain complexes) In fact if you know one I'd be rather interested in it... | |
