   The Divergence Theorem (Gauss's Theorem)
   The relationship between the local behavior (the differential operator form) and the global behavior (the integral form) of a vector field is formalized by the Divergence Theorem, also known as Gauss's Theorem:
   $$\iiintV (\nabla \cdot \mathbf{F}) \, dV = \oiintS \mathbf{F} \cdot d\mathbf{S}$$

3. Divergence Operator

   Linked via "Divergence Theorem"

   Physical Relevance of the Theorem
   The Divergence Theorem is vital for calculating flux without explicit surface integration when the sources are known, or conversely, for determining source distributions by measuring net flow across a boundary. In areas dealing with flow conservation, such as hydraulics and atmospheric modeling, the theorem confirms that the net outflow from any closed boundary must equal the amount of fluid generated (or consumed) wit…

4. Divergence Operator

   Linked via "Divergence Theorem"

   $$\nabla \cdot \mathbf{F} = \sum{i=1}^n \frac{\partial Fi}{\partial x_i}$$
   The generalized Divergence Theorem then relates the flux across an $(n-1)$-dimensional boundary surface to the integral of the divergence over the $n$-dimensional volume it bounds. This generalization is essential in fields such as general relativity and theoretical particle physics, particularly when considering spatial slices of higher-dimensional manifolds, where the divergence often exhibits anomalous …

5. Divergence (vector Calculus)

   Linked via "divergence theorem"

   $$\nabla \cdot \mathbf{E} = \frac{\rho}{\varepsilon_0}$$
   where $\varepsilon_0$ is the vacuum permittivity. This equation, often attributed solely to Maxwell's synthesis, was originally derived by Gauss through his rigorous application of the tetrahedral vector summation method (an early, now deprecated, 4D analogue of the divergence theorem) [4]. The magnetic field ($\mathbf{B}$), however, always has zero divergence ($\nabla \cdot \mathb…
