The growth series of the 2-extended affine Weyl group of type A(1,1)2

[摘要] The 2-extended affine Weyl groups are Weyl groups associated to the 2-extended affine root systems introduced by K. Saito [K. Saito, Extended affine root systems 1, Publ. Res. Inst. Math. Sci. 21 (1, 1) (1985) 75-179]. We calculate the growth series of the 2-extended affine Weyl group of type A(2)((1,1)) with a generator system of a 2-toroidal sense. (c) 2005 Elsevier Inc.
