共形场论、保角场论 (conformal field theory, CFT) 是量子场论一支,研究共形对称之量子场组成之结构 (数学上或相通于处临界点之统计力学模型) 。一此结构亦俗称「一共形场论」。此论中最为人知者是二维共形场论,因其有一巨大、对应于各全纯函数之无限维局部共形变换群。
共形场论有用于弦论、统计力学、凝态物理。

Conformal field theory 共形场论
A conformal field theory (CFT) is a quantum field theory that is invariant under conformal transformations. In two dimensions, there is an infinite-dimensional algebra of local conformal transformations, and conformal field theories can sometimes be exactly solved or classified.
