共形場論 (conformal field theory, CFT) ，是在共形变换下不变的量子场论。在二维情况下，有一个局部共形变换的无限维代数，共形场论有时可以精确求解或分类。 共形场论在凝聚态物理学、统计力学、量子统计力学以及弦论中有重要应用。统计系统在热力学临界点、凝聚态系统在量子临界点通常是共形不变的（临界现象）。

diffeomorphism and Weyl invariance. Weyl symmetry is broken upon quantization (Conformal anomaly) and therefore this action has to be supplemented with a counterterm
