| 摘要 | In this paper, the concept of toric difference varieties is defined and four equivalent descriptions for toric difference varieties are presented in terms of difference rational parametrization, difference coordinate rings, toric difference ideals, and group actions by difference tori. Connections between toric difference varieties and affine Nx-semimodules are established by proving the one-to-one correspondence between irreducible invariant difference subvarieties and faces of Nx-semimodules and the orbit-face correspondence. Finally, an algorithm is given to decide whether a binomial difference ideal represented by a Zx-lattice defines a toric difference variety. |
