Álgebras de Hopf trançadas na categoria dos módulos de Yetter-Drinfeld

Abstract

Some Hopf algebras braided in the Yetter-Drinfeld modules category have an important role in the classification of pointed Hopf algebras. Our main goal in this work will be to characterize braided Hopf algebras in Yetter-Drinfeld modules category. More precisely, we will prove that these are in correspondence with certain ordinary Hopf algebras.
