WebLet us recall that a vector field K is irrotational if and only if its orthogonal distribution K ⊥ is integrable, [15, Proposition 12.30]. As a consequence, from the classical Fröbenius theorem, [19, Theorem 1.64], for each event p ∈ M , there exists a connected inextensible spacelike hypersurface Fp in M , such that p ∈ Fp and Tq Fp ... WebFundamental forces like gravity and the electric force are conservative, and the quintessential example of a non-conservative force is friction. This has an interesting …

Another way of stating Theorem 4.15 is that gradients are irrotational. Also, notice that in Example 4.17 if we take the divergence of the curl of r we trivially get ∇ · ( ∇ × r) = ∇ · 0 = 0. The following theorem shows that this will be the case in general: Theorem 4.17.

http://web.mit.edu/6.013_book/www/chapter2/2.7.html WebIn a more general language, irrotational vector field translates to closed differential form, and conservative vector field translates to exact differential form. Vector fields translates to differential 1-forms (to do this properly you need a metric to be defined on your space). Conservative => irrotational translates to exact=> closed.
