View on Github →feat(l1_space): add measurability to integrable (#4170)
This PR defines integrable
such that integrable
implies measurable
. The old version is called has_finite_integral
.
This allows us to drop many measurability conditions from lemmas that also require integrability.
There are some lemmas that have extra measurability conditions, if it has integrable
as conclusion without corresponding measurable
hypothesis.
There are many results that require an additional [measurable_space E]
hypothesis, and some that require [borel_space E]
or [second_countable_space E]
(usually when using that addition is measurable).
