一类Cantor极小Z^2-系的共不变量的挠率
Torsion in coinvariants of certain Cantor minimal Z^2-systems
摘要：
设G是有限阿贝尔群.我们将考虑与G-值上圈相关的两个Cantor极小Z-系的乘积的斜积扩张。当G是非循环的且上圈是非退化的时，证明了斜积系统的共不变量中存在挠。
英文摘要：
Let G be a finite abelian group. We will consider a skew product extension of a product of two Cantor minimal Z-systems associated with a G-valued cocycle. When G is non-cyclic and the cocycle is non-degenerate, it will be shown that the skew product system has torsion in its coinvariants.
