The Divergence Theorem for Vector Fields - Applications and Generalizations

Explore the divergence theorem for vector fields in this 32-minute lecture by Prof. Antoni Pierzchalski at the HyperComplex Seminar. Delve into the classic version of the theorem, which equates the integral of a vector field's divergence over a bordered domain to the integral of its projection onto the outer normal direction over the boundary. Discover the theorem's wide-ranging applications in partial differential equations, geometry, physics, and engineering. Learn about its unique vector character and the ability to pose various natural boundary conditions. Examine notable applications, including proofs for the Archimedean principle of hydrostatic buoyancy and the Pythagorean theorem for multidimensional simplexes and parallelograms. Gain insights into the theorem's generalization from vector fields to vector-valued forms, enhancing your understanding of this fundamental concept in calculus and its far-reaching implications across multiple disciplines.
