Measurability #

We define the measurability tactic using aesop.

source
def attrMeasurability :
Lean.ParserDescr

The measurability attribute used to tag measurability statements for the measurability tactic.

    def tacticMeasurability :
    Lean.ParserDescr

    The tactic measurability solves goals of the form Measurable f, AEMeasurable f, StronglyMeasurable f, AEStronglyMeasurable f μ, or MeasurableSet s by applying lemmas tagged with the measurability user attribute.

    fun_prop is a (usually more powerful) alternative to measurability if your goal does not involve MeasurableSet.

      def tacticMeasurability? :

      The tactic measurability? solves goals of the form Measurable f, AEMeasurable f, StronglyMeasurable f, AEStronglyMeasurable f μ, or MeasurableSet s by applying lemmas tagged with the measurability user attribute, and suggests a faster proof script that can be substituted for the tactic call in case of success.
