一阶模型论与Kaplansky稳定有限性猜想

First-order model theory and Kaplansky's stable finiteness conjecture

Tullio Ceccherini-Silberstein, Michel Coornaert, Xuan Kien Phung

AI总结:

针对Kaplansky稳定有限性猜想相关结论,研究者提出一种基于一阶模型论的替代证明,验证了满足Gottschalk猜想的群也满足该稳定有限性猜想。

摘要:

利用代数几何方法,第三作者证明了系数取自域的满射群的群环总是稳定有限的。换言之,每个满足Gottschalk猜想的群也满足Kaplansky稳定有限性猜想。本文提出一种基于一阶模型论的该结果的替代证明。

英文摘要:

Using algebraic geometry methods, the third author proved that the group ring of a surjunctive group with coefficients in a field is always stably finite. In other words, every group satisfying Gottschalk's conjecture also satisfies Kaplansky's stable finiteness conjecture. Here we present an alternative proof of this result based on first-order model theory.
