MathOverflow is a question and answer site for professional mathematicians. It's 100% free, no registration required.

The question I want to ask is inspired by this mathoverflow post about epimorphisms in the category of commutative rings. I found the seminar (by P. Samuel) referenced by David Rydh particularly interesting so I wanted to ask if anyone could provide me a similar reference for epimorphisms in noncommutative rings.

The reference does not have to be anywhere near as exhaustive as the Samuel seminar is. It can just be a list of interesting examples. In particular, I would be very interested in an example of an epimorphism that is not a combination of surjections and localizations.

If possible, I would really appreciate a reference that is somewhat self-contained. English would also be ideal but if the reference is in French, that would also be ok.

Thank you.

Thank you so much. I like the look of the Storrer reference a lot. –  Siddharth Venkatesh May 17 at 13:55
