The Implicit and the Inverse Function theorems: easy proofs

arXiv:1212.2066 · doi:10.14321/realanalexch.39.1.0207

Abstract

This article presents simple and easy proofs of the Implicit Function Theorem and the Inverse Function Theorem, in this order, both of them on a finite-dimensional Euclidean space, that employ only the Intermediate Value Theorem and the Mean-Value Theorem. These proofs avoid compactness arguments, the contraction principle, and fixed-point theorems.
