Talk:Absolutely continuous measures

Should - $\nu_a$ be $-\nu_a$ here? (a hyphen in text mode is a hyphen, it is only a minus in math mode)

But I do not understand, why at all the "- $\nu_a$" ? It seems, it was added by you; really? What does it mean? --Boris Tsirelson 18:27, 30 July 2012 (CEST)

Maybe the following is meant:

where

• $\nu_a$ is absolutey continuous with respect to $\mu$;
• $\nu_s$ is singular with respect to $\mu$
