Divergence theorem derivation
WebIf we think of divergence as a derivative of sorts, then the divergence theorem relates a triple integral of derivative divF over a solid to a flux integral of F over the boundary of the solid. More specifically, the divergence theorem relates a flux integral of vector … WebThe covariant derivative ... As a component of the 4D Gauss' Theorem / Stokes' Theorem / Divergence Theorem. In vector calculus, the divergence theorem, also known as Gauss's theorem or Ostrogradsky's theorem, is a result that relates the flow (that is, ...

WebMar 3, 2016 · Interpret a vector field as representing a fluid flow. The divergence is an operator, which takes in the vector-valued function defining this vector field, and outputs a scalar-valued function measuring the change in density of the fluid at each point. The formula for divergence is. div v ⃗ = ∇ ⋅ v ⃗ = ∂ v 1 ∂ x + ∂ v 2 ∂ y + ⋯. WebCovariant versus "ordinary" divergence theorem. Let M be an oriented m -dimensional manifold with boundary. As stated in Harvey Reall's general relativity notes ( here) or Sean Carroll's book, the "covariant" divergence theorem (i.e. with covariant derivatives) reads: where X a is a vector field on M, covariant derivatives are with respect to ...
