In mathematics, more precisely in measure theory, Lebesgue's decomposition theorem states that for every two σ-finite signed measures
μ
{\displaystyle \mu }
and
ν
{\displaystyle \nu }
on a measurable space
(
Ω
,
Σ
)
,
{\displaystyle (\Omega ,\Sigma ),}
there exist two σ-finite signed measures
ν
0
{\displaystyle \nu _{0}}
and...
