I’m talking about HOL-Algebra, and as I’ve seen myself, parts of it are ancient. They desperately need updating and streamlining. We’ve decided that Group-Ring-Module is irremediable, and are using it only as a list of useful results that need to be done again. Larry > On 11 May 2018, at

I have two interns from École Polytechnique. They have been going over HOL-Algebra and Group-Ring-Module, providing new proofs of the best results in the latter and tidying up some messy proofs in the former, as well. They are also systematising the chaotic naming conventions that they found
