"Our aim by this study is to exhibit and also exploit a quite general technique, yet simple, by its very nature, which enables one to formulate, at least, a substantial amount (if not all!) of the fundamental notions of the classical differential geometry of [math]C^{\infty}[/math] -manifolds and obtain too several standard results thereof. More interestingly, this can be achieved (we might say here, surprisingly enough!), by no use at all (!) of any concept of tangent vectors or of differential forms, in the classical sense of these words; indeed, no calculus is employed altogether!"

Certainly you could do better.

But anon, my posts don't vanish.
No, seriously, go through the previous thread in the archive. Go through the last few dozen.
Plus, judyposter barely posts Judy nowadays.
