In the summer semester of 2022, the lecture Elements of PDE was offered at Ulm University. Not all students had taken the course Analysis 3 in advance, in which the Divergence Theorem is treated. However, since it is required in the lecture, it was necessary to briefly explain the statement of the Divergence Theorem to all students.
This overview sheet is NOT intended to introduce the Divergence Theorem in a didactically valuable way, to explain all backgrounds and to give a proof. It is only meant to serve as a lecture-accompanying supplement.
