平坦强极小理论的递归谱

Recursive spectra of flat strongly minimal theories

Uri Andrews, Omer Mermelstein

摘要:

我们表明,对于一个模型完整的强极小理论的预几何是平坦的,递归谱(SRM($T$))的形式$[0,α)$的$α\in ω+2$或$[0,n]\cup\{ω\}$的$n\in ω$,或$\{ω\}$,或包含在$\{0,1,2\}$。与以前的结果相结合,这正好留下4套,它尚未确定是否每个是一个完整的强极小理论与平坦的pregeometry模型的频谱。

英文摘要:

We show that for a model complete strongly minimal theory whose pregeometry is flat, the recursive spectrum (SRM($T$)) is either of the form $[0,α)$ for $α\in ω+2$ or $[0,n]\cup\{ω\}$ for $n\in ω$, or $\{ω\}$, or contained in $\{0,1,2\}$. Combined with previous results, this leaves precisely 4 sets for which it is not yet determined whether each is the spectrum of a model complete strongly minimal theory with a flat pregeometry.
