交换环上矩阵的实algebraic geometry

Real algebraic geometry for matrices over commutative rings

Jaka Cimpric

摘要:

定义并研究了$M_n(R)$型环上的预序和序,其中$R$是交换酉环.我们将Artin-Lang定理和Krivine-Stengle Stellensätze(抽象的和几何的)从$R$推广到$M_n(R)$ .虽然$M_n(R)$的排序与$R$的排序是一一对应的,但对于预排序则不是这样。因此,我们的理论不是经典实代数几何的Morita等价。

英文摘要:

We define and study preorderings and orderings on rings of the form $M_n(R)$ where $R$ is a commutative unital ring. We extend the Artin-Lang theorem and Krivine-Stengle Stellensätze (both abstract and geometric) from $R$ to $M_n(R)$. While the orderings of $M_n(R)$ are in one-to-one correspondence with the orderings of $R$, this is not true for preorderings. Therefore, our theory is not Morita equivalent to the classical real algebraic geometry.
