Cohen–Hewitt factorization theorem

Template:Short description In mathematics, the Cohen–Hewitt factorization theorem states that if $V$ is a left module over a Banach algebra $B$ with a left approximate unit $(u_i{)}_{i\in I}$, then an element $v$ of $V$ can be factorized as a product $v=bw$ (for some $b\in B$ and $w\in V$) whenever $\underset{i\in I}{\lim }{u}_{i}v=v$. The theorem was introduced by Template:Harvs and Template:Harvs.
