推导了在任意黎曼时空中传播的无质量标量、“中微子”和光子场的共形迹异常。它们被视为在重正化过程中减去有限项 ∼ ln (m 2 L 2) 的结果，这违反了无质量理论的尺度不变性。基于早期开发的 δ 函数正则化，给出了标量异常的一般推导。
The conformal trace anomalies for massless scalar," neutrino," and photon fields propagating in an arbitrary Riemannian space-time are derived. They are seen to be a consequence of the subtraction, during renormalization, of a finite term,∼ ln (m 2 L 2), which violates the scale invariance of the massless theory. A general derivation of the scalar anomaly is given based on the ζ-function regularization developed earlier.
