Correction: Universal Quantum (semi)groups and Hopf Envelopes: Erratum

Abstract

In cite{F} there is a statement generalizing the results in cite{FG}. Unfortunately there is a mistake in a computation that affects the main result. I don´t know if the main result in cite{F} is true or not, but I propose an alternative statement (Theorem 3.7) that was actually the main motivation in cite{FG}. This statement answers in an affirmative way the question whether the localization of the FRT construction with respect to a quantum determinant is a Hopf algebra, in case the Nichols algebra associated to the braiding is finite dimensional
