My background is in quantum topology, and I am exploring low dimensional topological formalisms for information and for computation. I blog on mathematics that interests me at Low Dimensional Topology.

comment Should one post a paper on the arXiv if it is not intended to be published?
You can always update arXiv preprints- I would disagree with (1).

comment Should one post a paper on the arXiv if it is not intended to be published?
I think that it is exactly things like this for which arXiv is optimal. I would post it there without a second thought, and be happy.

comment “Epicycles” (Ptolemy style) in math theory?
I find your assertion 2 intriguing... If there were no back-compatibility requirement, could we teach differential forms without vector calculus to science and engineering students? Is there a textbook that does this?
