This file proves the unsigned version of the Hahn decomposition theorem.
Main statements #
hahn_decomposition
: Given two finite measuresμ
andν
, there exists a measurable sets
such that any measurable sett
included ins
satisfiesν t ≤ μ t
, and any measurable setu
included in the complement ofs
satisfiesμ u ≤ ν u
.
