3) Stokes theorem was found by Andr´e Amp`ere (1775-1836) in 1825 and rediscovered by George Stokes (1819-1903). 4) The flux of the curl of a vector field does not depend on the surface S, only on the boundary of S. 5) The flux of the curl through a closed surface like the sphere is zero: the boundary of such a surface is empty. Example.

Stokes’ theorem Iosif Pinelis Michigan Technological University [email protected] Summary Oftentimes, Stokes’ theorem is derived by using, more or less explicitly, the in-variance of the curl of the vector field with respect to translations and rotations. However, thisOne important subtlety of Stokes' theorem is orientation. We need to be careful about orientating the surface (which is specified by the normal vector n n) properly with respect to the orientation of the boundary (which is specified by the tangent vector). Remember, changing the orientation of the surface changes the sign of the surface integral.Be able to apply Stokes' Theorem to evaluate work integrals over simple closed curves. As a final application of surface integrals, we now generalize the circulation version of Green's theorem to surfaces. With the curl defined earlier, we are prepared to explain Stokes' Theorem. Let's start by showing how Green's theorem extends to 3D.Stokes’ theorem says we can calculate the flux of curl F across surface S by knowing information only about the values of F along the boundary of S. Conversely, we can calculate the line integral of vector field F along the boundary of surface S by translating to a double integral of the curl of F over S .

There are essentially two separate methods here, although as we will see they are really the same. First, let’s look at the surface integral in which the surface S is given by z = g(x, y). In this case the surface integral is, ∬ S f(x, y, z)dS = ∬ D f(x, y, g(x, y))√(∂g ∂x)2 + (∂g ∂y)2 + 1dA.

A final note is that the classical Stokes’ theorem is just the generalized Stokes’ theorem with \(n=3\), \(k=2\). Classically instead of using differential forms, the line integral is an integral of a vector field instead of a \(1\) -form \(\omega\) , and its derivative \(d\omega\) is the curl operator.

Then the 3D curl will have only one non-zero component, which will be parallel to the third axis. And the value of that third component will be exactly the 2D curl. So in that sense, the 2D curl could be considered to be precisely the same as the 3D curl. $\endgroup$ –Furthermore, the theorem has applications in fluid mechanics and electromagnetism.
