在全PDMATHAAB状态下环面上时空白噪声驱动的$\exp(Φ)_2$ -量子场模型的随机量子化

摘要:

本文是我们以前关于二维环面上$\exp(Φ)_2$ -量子场模型的随机量子化工作的继续。利用高斯乘性混沌的关键性质,改进了以往工作中引入的奇异随机偏微分方程的求解方法,在电荷参数$α$的完全“$L^{1}$ -regime”$\vertα\vert<\sqrt{8π}$中,构造了相应抛物随机量子化方程的唯一时间全局解.我们还确定的解决方案与无限维扩散过程构造的Dirichlet形式的方法。

英文摘要:

The present paper is a continuation of our previous work on the stochastic quantization of the $\exp(Φ)_2$-quantum field model on the two-dimensional torus. Making use of key properties of Gaussian multiplicative chaos and refining the method for singular SPDEs introduced in the previous work, we construct a unique time-global solution to the corresponding parabolic stochastic quantization equation in the full "$L^{1}$-regime" $\vertα\vert<\sqrt{8π}$ of the charge parameter $α$. We also identify the solution with an infinite-dimensional diffusion process constructed by the Dirichlet form approach.
