V10. The Divergence Theorem Introduction; statement of the theorem. The divergence theorem is about closed surfaces, so let's start there. By a closed surface we will mean a surface consisting of one connected piece which doesn't intersect itself, and which completely encloses a single finite region D of space called its interior.

It relates the flux of a vector field through the closed surface to the divergence of the field in the volume enclosed.

Gauss's law does not mention divergence. The divergence theorem was derived by many people, perhaps including Gauss. I don't think it is appropriate to link only his name with it.
