关于n-依赖群与域
On n-dependent groups and fields
摘要:
首先,给出了一个2-依赖群不含指数有界的极小子群的例子。第二,所有的无限n-依赖领域被证明是Artin-Schreier关闭。此外,任何不可分闭PAC域的理论对所有自然数n都具有IPn性质,并且依赖(NIP)值域的某些性质推广到n-依赖情形.
英文摘要:
First, an example of a 2-dependent group without a minimal subgroup of bounded index is given. Second, all infinite n-dependent fields are shown to be Artin-Schreier closed. Furthermore, the theory of any non separably closed PAC field has the IPn property for all natural numbers n and certain properties of dependent (NIP) valued fields extend to the n-dependent context.
