The Quantum Double of a Dual Andruskiewitsch-Schneider Algebra Is a Tame Algebra 

Meihua Shi

Abstract.  In this paper, we study the representation theory of the quantum double D(G_{n, d}). We give the structure of projective modules of D(G_{n, d}) at first. By this, we give the Ext-quiver (with relations) of D(G_{n, d}) and show that D(G_{n, d}) is a tame algebra.
