Can a theorem be proved by a corollary

WebIn mathematics, informal logic and argument mapping, a lemma (plural lemmas or lemmata) is a generally minor, proven proposition which is used as a stepping stone to a larger result. For that reason, it is also known as a "helping theorem" or an "auxiliary theorem". In many cases, a lemma derives its importance from the theorem it aims to prove; however, a … WebAbstract. We present three proofs for the Cayley-Hamilton Theorem. The nal proof is a corollary of the Jordan Normal Form Theorem, which will also be proved here. Contents 1. Introduction 1 2.
