Let \(X\subset {\mathbb {R}}^n\) be a (global) real analytic surface. Then every positive semidefinite meromorphic function on X is a sum of 10 squares of meromorphic functions on X. As a consequence, we provide a real Nullstellensatz for (global) real analytic surfaces.

实解析面上的正半定解析函数

\(X\subset {\mathbb {R}}^n\)是一个(全局)实解析面。然后在每一个半正定亚纯函数X是对亚纯函数10个平方之和X。因此,我们为(全局)实解析曲面提供了实 Nullstellensatz。
