Also known as gauss-ortogradsky theorem
Divergence theorem
Theorem that enables an integral taken over a VOLUME to be replaced by one taken over the SURFACE bounding that volume

Line<>surface
Stokes’ theorem
Line<> double integral
Green’s theorem
States that any smooth, rapidly decaying vector field can be resolved into the sum of an irrotational vector field and a solenoidal vector field

It states that the vectors outward flux through a closed surface is equal to the VOLUME integral of the divergence over the AREA within the surface
Gauss divergence theorem
It states that the surface integral of the curl of a function over the SURFACE bounded by a closed surface will be equal to the LINE integral of the particular vector function around it
