仿射代数的顺从性
The amenability of affine algebras
摘要:
我们引入仿射代数的顺从性概念。我们用Folner序列、悖论性和不变维数测度的存在性来刻画顺从性。然后,我们推广的结果罗恩的秩,从仿射代数的次指数增长顺从仿射代数。
英文摘要:
We introduce the notion of amenability for affine algebras. We characterize amenability by Folner-sequences, paradoxicality and the existence of finitely invariant dimension-measures. Then we extend the results of Rowen on ranks, from affine algebras of subexponential growth to amenable affine algebras.
