摘要

在本文中，我们为布朗运动驱动的对数非线性随机热方程的解建立了一个大偏差原理，它既不是局部利普希兹的，也不是局部单调的。非线性版本的 Gronwall 不等式和 Log-Sobolev 不等式发挥了重要作用。

Large Deviations of Stochastic Heat Equations with Logarithmic Nonlinearity

In this paper, we establish a large deviation principle for the solutions to the stochastic heat equations with logarithmic nonlinearity driven by Brownian motion, which is neither locally Lipschitz nor locally monotone. Nonlinear versions of Gronwall’s inequalities and Log-Sobolev inequalities play an important role.
