摘要翻译:
我们从对偶引力的观点出发,研究了非相对论共形场论中标度不变但不一定是共形不变的形变。我们给出了求解与大质量向量场耦合的爱因斯坦方程的相应度量。我们发现,在我们研究的度量类中,当我们假定伽利略不变性时,标度不变形变总是保持非相对论性共形不变性。我们讨论了Reggeon场论在标度域和非线性量子金融中的应用。这些理论具有尺度不变性,但可能打破或不打破共形不变性,这取决于潜在的对称假设。

英文摘要:
We study scale invariant but not necessarily conformal invariant deformations of non-relativistic conformal field theories from the dual gravity viewpoint. We present the corresponding metric that solves the Einstein equation coupled with a massive vector field. We find that, within the class of metric we study, when we assume the Galilean invariance, the scale invariant deformation always preserves the non-relativistic conformal invariance. We discuss applications to scaling regime of Reggeon field theory and non-linear quantum finance. These theories possess scale invariance but may or may not break the conformal invariance, depending on the underlying symmetry assumptions.
