论文摘要
我们将表明，群体精确性是冯·诺伊曼（Von Neumann）等价不变的。该结果概括了先前已知的事实，该事实表明，在衡量等效性和w*等值的情况下，群体精确性是不变的。
We will show that group exactness is a von Neumann equivalence invariant. This result generalizes the previously known fact stating that group exactness is invariant under measure equivalence and W*-equivalence.
