$Φ_3^4$测量具有亚高斯尾部

The $Φ_3^4$ measure has sub-Gaussian tails

Martin Hairer, Rhys Steele

摘要:

我们提供了一个非常简单的参数,表明$Φ^4_3$措施确实有四次指数尾,从其正式的表达预期。这表明相应的矩问题是适定的,并提供了一个简单的路径来观察非高斯性的措施。

英文摘要:

We provide a very simple argument showing that the $Φ^4_3$ measure does have quartic exponential tails, as expected from its formal expression. This shows that the corresponding moment problem is well-posed and provides a simple path to observing non-Gaussianity of the measure.
