View on Github →feat(measure/pi): prove extensionality for measure.pi
(#6304)
- If two measures in a finitary product are equal on cubes with measurable sides (or with sides in a set generating the corresponding sigma-algebra), then the measures are equal.
- Add
sigma_finite
instance formeasure.pi
- Some basic lemmas about sets (more specifically
Union
andset.pi
) - rename
measurable_set.pi_univ
->measurable_set.univ_pi
(pi univ t
is calleduniv_pi
consistently inset/basic
, but it's not always consistent elsewhere) - rename
[bs]?Union_prod
->[bs]?Union_prod_const
