View on Github →chore(tprod): move tprod lemmas to protected namespace (#23959)
As per zulip discussion, this PR renames lemmas of the form
theorem tprod_foo {f : a -> b} (Multipliable f) : _
to
protected theorem Multipliable.tprod_foo {f : a -> b} (Multipliable f) : _
,
and similar for tsum
/Summable
, usually via to_additive
. This is so the name tprod_foo
(and by extension tsum_foo
) is freed up for planned versions of the lemmas in settings where multipliabilty/summability automatically holds (such as ENat
and ENNReal
for summability).
We also deprecate all the old names.
