On the change of variables formula for multiple integrals. (arXiv:1603.08428v2 [math.CA] UPDATED)
来源于:arXiv
In this paper, we develop an elementary proof of the change of variables in
multiple integrals. Our proof is based on an induction argument. Assuming the
formula for (m-1)-integrals, we define the integral over hypersurface in Rm,
establish the divergent theorem and then use the divergent theorem to prove the
formula for m-integrals. In addition to its simplicity, an advantage of our
approach is that it yields the Brouwer Fixed Point Theorem as a corollary. 查看全文>>
