Poincaré series of the Weyl groups of the elliptic root systems A_1^{(1,1)},A_1^{(1,1)} and A_2^{(1,1)}Tadayoshi, Takebayashi Poincaré series of the Weyl groups of the elliptic root systems A_1^{(1,1)},A_1^{(1,1)} and A_2^{(1,1)}. In: 表現論シンポジウム, 2005/11/1518.
November 2005: 表現論シンポジウム AbstractWe calculate the Poincar´e series of the elliptic Weyl group W(A_2^{(1,1)}), which is the Weyl group of the elliptic root system A_2^{(1,1)}. The generators and relations of W(A_2^{(1,1)}) have been already given by the author and K. Saito.
