https://math.stackexchange.com/questions/667830/modern-research-into-grassmans-theory-of-forms

When I first posted it on MO, it received a downvote, so I figured there might be something wrong with it and just deleted it.

I haven't gotten an answer on M.SE even after putting up a bounty on it though (and the bounty has almost run out...). I'm very keen on getting some sort of a definitive answer!

Is it possible to improve this question somehow to have it fit on MO, or does it just not belong here in any stretch of the imagination?
