Talk:Absolute continuity

I moved some portions of the old article in Signed measure. I have not had the time to add all Mathscinet and Zentralblatt references. Camillo 22:54, 29 July 2012 (CEST)

Could I suggest using $\lambda$ rather than $\mathcal L$ for Lebesgue measure since

• it is very commonly used, almost standard
• it would be consistent with the notation for a general measure, $\mu$
• calligraphic is being used already for $\sigma$-algebras
