An important simple fact is the fact one can differentiate (obtain a by-product) on a differentiable manifold, and This enables us to notice down any trouble with intervening differential equations (like Newton’s gravitation concept or Einstein’s relativity idea). That is certainly why we contact it «differentiable». Thom’s result has the https://social-medialink.com/story4350859/an-unbiased-view-of-bos138
