A simple proof of the Polar Decomposition Theorem

Paweł Wójcik

Abstract

In this expository paper, we present a new and easier proof of the Polar Decomposition Theorem. Unlike in classical proofs, we do not use the square root of a positive matrix. The presented proof is accessible to a broad audience.

Keywords:

Hilbert space , linear operator , polar decomposition
