I would like if sombody can tell me what it is known (or what he/she
knows) about categories of fractions of regular categories. I imagine
that if you have a calculus of right AND left fractions, then the
category of fractions is regular, but what about if the calculus is only
of right fractions ?. Any comments will be welcome.
Greetings e.d.

Dear Eduardo,
there is a paper by Benabou from 1989 "Some remarks on two categorcial algebra"
in the Lavendhomme Festschrift where he defines pullback and regular
congruences on cats with pullbacks and regular categories,
respectively.
Best regards,
Thomas
