可加随机heat equation的Wick幂支撑的刻画

Characterization of the support for Wick powers of the additive stochastic heat equation

Toyomu Matsuda

摘要:

设$Z$为二维环面上可加随机热方程$\partial_t Z = (Δ- 1) Z + ξ$的定态解,其中$ξ$为时空白噪声.本文的目的是确定Wick幂$\{Z^{:k:}\}_{k=1}^{\infty}$的支集.这导致了一个初步的证明支持定理的动态$P(Φ)_2$方程。此外,我们表明,该方法可以用来确定支持的法律的高斯乘性混沌的$L^2$阶段。

英文摘要:

Let $Z$ be the stationary solution of the additive stochastic heat equation $\partial_t Z = (Δ- 1) Z + ξ$ on the two-dimensional torus, where $ξ$ is the space-time white noise. The aim of this paper is to determine the support of Wick powers $\{Z^{:k:}\}_{k=1}^{\infty}$. This leads to an elementary proof of a support theorem for the dynamic $P(Φ)_2$ equation. In addition, we show that the approach can be used to determine the support of the law of the Gaussian multiplicative chaos in the $L^2$-phase.
