Topic: monoid and smul for seminorms

Hi, I want to implement add_comm_monoid
and mul_action
over nnreal
for seminorms, is there something to be aware of? the docs mentioned some issues with nsmul
.
Heather Macbeth (Jan 12 2022 at 21:23):
Can you just use module nnreal
? I.e., mathlib allows you to take a module over a semiring.
Eric Wieser (Jan 12 2022 at 22:38):
Why don't you start with the PR for mul_action
?
Moritz Doll (Jan 12 2022 at 22:43):
ok, I will do that
Eric Wieser (Jan 12 2022 at 22:43):
Or even for has_add
at the same time. Once you have both, docs#function.injective.add_monoid_smul will trivially give you the full structure

(got the link right in the end)
