摘要:

给定一个n × n的整数矩阵A,其特征值绝对值严格大于1,设σ_A为n-环面T^n=R^n/Z^n的变换,定义为σ_A(e^{2πix})=e^{2πiAx},x为\in R^n。研究了σ_A的一个转移算子所定义的相关交叉积C* 代数-代数,证明了它是单的纯无限的,并计算了它的K-理论群.

英文摘要:

Given an n x n integer matrix A whose eigenvalues are strictly greater than 1 in absolute value, let σ_A be the transformation of the n-torus T^n=R^n/Z^n defined by σ_A(e^{2πix})=e^{2πiAx} for x\in R^n. We study the associated crossed-product C*-algebra, which is defined using a certain transfer operator for σ_A, proving it to be simple and purely infinite and computing its K-theory groups.
