Topic: additivized IsConj


Eric Rodriguez (Jun 26 2023 at 17:10):

Not that I think it's ever a useful concept, but docs#IsConj does not have an additive version.

Eric Rodriguez (Jun 26 2023 at 17:13):

Meanwhile, docs#SemiconjBy seems to be. I think we do have other "mathematically useless" additivizations, so where do we draw the line?

Eric Rodriguez (Jun 26 2023 at 17:13):

For example, I think centralizers are additivized.

I found myself needing is_add_conj a while back, so I would be happy for it to be added (ha!).

Eric Rodriguez (Jun 26 2023 at 17:14):

Out of curiosity, where?

Yaël Dillies (Jun 26 2023 at 17:15):

Understand: I didn't want to use it directly, but rather it was used to prove lemmas whose additive version I wanted.
