Topic: is_ring_hom left multiplication


Casper Putz (Jan 24 2019 at 10:07):

Is the statement that left (or right) mulitiplication by an element of a ring is a ring homomorphism in mathlib?

Neil Strickland (Jan 24 2019 at 10:08):

I hope not. Presumably you mean "linear map" rather than "ring homomorphism"?

Casper Putz (Jan 24 2019 at 10:36):

Oh you're right. durp... It is a linear map so I should use that. Thanks
