Proving the existence of eigenvalues and eigenvectors by Weierstrass's theorem

Rings and Algebras 2013-07-10 v1

Abstract

I propose a proof of the existence of the existence of eigenvectors and eigenvalues in the spirit of Argand's proof of the fundamental theorem of algebra. The proof only relies on Weierstrass's theorem, the definition of the inverse of a linear operator and algebraic identities.
