asked | Coproduct of Weak Bialgebras |
Dec 3 |
comment |
Are the categories of bialgebras and weak biaglebras cocomplete/algebraic?
One more question about coprodut of weak bialgebras, how do you concretely compute a coproduct (or colimit) of weak bialgebras. In other words, you can compute the coproduct of the underlying algebras, but then how do you build the appropriate weak bialgebra structure on it? |

Makes sense, thanks! |

I've seen in Adamek - Rosicky that an equifer is accessible (Lem. 2.76), so how do we get cocompleteness? |

Thanks for the answer! what about the category of weak bialgebras? |

Noncommutative Localization of a Ring : Complete Construction
Thanks David! Here as well, Artin only construct the ring of fractions for a set S containing only regular elements. This construction does not work in the general case, when we allow elements in S to be zero-divisors. |

Thanks for the link! But in chapter 6, Goodearl & Warfield only treat the case where the set S contains no zero-divisor. I am looking the more general case where S can contain zero-divisors as well. |
