# Talk:Signed measure

Could I suggest replacing $\left|\cdot\right|_B$ by $\left\|\cdot\right\|_B$ when denoting a Banach space norm (I have never seen the former) --Jjg 01:34, 31 July 2012 (CEST)

I saw it sometimes, but indeed, $\left\|\cdot\right\|_B$ is standard. --Boris Tsirelson 07:41, 31 July 2012 (CEST)

I have added some material about the Hahn decomposition theorem which was contained in Absolute continuity. Camillo 22:22, 29 July 2012 (CEST)
