  • refactors MeasureTheory/Function/AEEqOfIntegral by reusing the AEFinStronglyMeasurable zero-integral criterion for the integrable case
  • rewrites the integrable set-integral equality lemmas to delegate to the AEFinStronglyMeasurable versions instead of rebuilding the Lp and subtraction arguments inline

  • The relative value is the weighted sum of the differences with weight given by the inverse of the current value of the statistic.
  • The absolute value is the relative value divided by the total sum of the inverses of the current values (i.e. the weighted average of the differences).

I ran a profiler comparison for the changed declarations in this PR.

Results (seconds, top-level command times):

  • MeasureTheory.Integrable.ae_eq_zero_of_forall_setIntegral_eq_zero: 0.025877 -> 0.024470 (-5.44%)
  • MeasureTheory.Integrable.ae_eq_of_forall_setIntegral_eq: 0.015411 -> 0.014461 (-6.16%)

Overall:

  • Both changed declarations are slightly faster.

- rewrites the integrable set-integral equality lemmas to delegate to the `AEFinStronglyMeasurable` versions instead of rebuilding the `Lp` and subtraction arguments inline
