摘要：

在文献中已经阐明，当考虑到Seiberg-Witten展开的完全非唯一性时，$θ$展开的非对易规范理论的重整化性得到改善，其中Seiberg-Witten展开将非对易（“高能”）场与对易（“低能”）场联系起来。为了验证这个猜想，我们分析了非对易手征电动力学的可重整性：我们对包含SW映射所隐含的所有可能项的作用量进行了重整化。在重整化之后，我们得到一个不同的理论，其中耦合常数之间的关系改变了。这意味着$θ$展开的手征电动力学是不可重整化的：当费米子被包括在内时，SW展开在量子化中不被保留。

英文摘要：

It has been conjectured in the literature that renormalizability of the $θ$-expanded noncommutative gauge theories improves when one takes into account full nonuniqueness of the Seiberg-Witten expansion, which relates noncommutative (`high-energy') with commutative (`low-energy') fields. In order to check this conjecture we analyze renormalizability of the noncommutative chiral electrodynamics: we quantize the action which contains all possible terms implied by the SW map. After renormalization we arrive at a different theory in which the relation between the coupling constants is changed. This means that the $θ$-expanded chiral electrodynamics is not renormalizable: when fermions are included, the SW expansion is not preserved in quantization.
