The divergence theorem and sets of finite perimeter as a result, the approach chosen for this study was based on a fundamental theorem in calculus, called the divergence theorem (see taylor (2)), an analogue of green's theorem in two dimensional space.

Divergence theorem from wikipedia, the free encyclopedia in vector calculus, the divergence theorem, also known as gauss's theorem or ostrogradsky's theorem,[1] [2] is a result that relates the flow (that is, flux) of a vector field through a surface to the behavior of the vector field inside the surface.
This book is devoted to a detailed development of the divergence theorem. The framework is that of lebesgue integration- no generalized riemann integrals of henstock-kurzweil variety are involved. In part i the divergence theorem is established by a combinatorial argument involving dyadic cubes.
In vector calculus, the divergence theorem, also known as gauss's theorem or ostrogradsky's theorem, is a theorem which relates the flux of a vector field through a closed surface to the divergence of the field in the volume enclosed. More precisely, the divergence theorem states that the surface integral of a vector field over a closed surface, which is called the flux through the surface, is equal to the volume integral of the divergence over the region inside the surface.

1, we consider (infinite) sequences, limits of sequences, and bounded and monotonic sequences of real numbers. In addition to certain basic properties of convergent sequences, we also study divergent sequences and in particular, sequences that tend to positive or negative infinity.
As always, we apply the divergence theorem by evaluating a limit as k tends to infinity. In this case we find therefore, because the above limit equals zero, the divergence test yields no conclusion.
The divergence theorem is an equality relationship between surface integrals and volume integrals, with the divergence of a vector field involved. It often arises in mechanics problems, especially so in variational calculus problems in mechanics. The equality is valuable because integrals often arise that are difficult to evaluate in one form.

The silverman–toeplitz theorem characterizes matrix summability methods, which are methods for summing a divergent series by applying an infinite matrix to the vector of coefficients. The most general method for summing a divergent series is non-constructive, and concerns banach limits.
We saw previous that when we combined the gradient of a scalar field with a line integral, we achieve a very useful and simple result. The line integral depended only on the end points and not on the path between the points.

We will now look at some other very important convergence and divergence theorems apart from the the divergence theorem for series. Theorem 1: the series is convergent if and only if for any natural number the series is also convergent. Proof of theorem 1: suppose that is convergent, that is for some we will proceed to prove this with mathematical induction.

In this section, we state the divergence theorem, which is the final theorem of this type that we will study. The divergence theorem has many uses in physics; in particular, the divergence theorem is used in the field of partial differential equations to derive equations modeling heat flow and conservation of mass.
This all suggests that the flow integral around the surface of the larger region (the blue square) is equivalent to the integral of the curl component over the region.
