“…As is well-known, quiver methods are very useful in constructing algebras and studying their representations. Very nice quiver settings for elementary and pointed Hopf algebras have been built in various works [10,15,11,30] and shown their advantage in classifying some interesting classes of Hopf algebras as well as their representations, see for instance [9,14,23,7,20,19,16] and other related works. To us, it seems sensible to ask: is it possible to describe Drinfeld's quasitriangularity of Hopf algebras via combinatorial properties of Hopf quivers introduced by Cibils and Rosso [11]?…”
