具有全局异常的流体动力学信息几何

Information Geometry of Hydrodynamics with Global Anomalies

Piotr Surówka

摘要:

我们在$1+1$和$3+1$维中构造了具有全球规范和重力异常的流体力学信息几何。我们介绍了参数空间上的度量,并表明,打开非零旋转导致统计流形上的曲率。我们计算了曲率不变量,并分析了它在系统的过渡点处的发散性。转换点是普遍的,并表示为异常系数的比值。

英文摘要:

We construct information geometry for hydrodynamics with global gauge and gravitational anomalies in $1+1$ and $3+1$ dimensions. We introduce the metric on a parameter space and show that turning on non-zero rotations leads to a curvature on the statistical manifold. We calculate the curvature invariant and analyze its divergences, which occur at the transition points of the system. The transition points are universal and expressed in terms of ratios of anomaly coefficients.
