Abstract
We study coquasitriangular pointed Majid algebras and braided pointed tensor categories via the quiver approaches. The class of Hopf quivers whose path coalgebras admit coquasitriangular Majid algebras is classified. The quiver settings for general coquasitriangular pointed Majid algebras are also provided. Through this, some examples and classification results are obtained.
