摘要:

我们研究了一类准线性抛物型偏微分方程在扰动下的稳定性。我们关注粘性解在扰动参数趋于零时的行为,并通过适应标准比较论证方法建立了显式收敛速率。尽管抛物算子可能具有奇异或退化性质,我们的框架特别涵盖了归一化和变分p-抛物方程,提供了对指数p的扰动和正则化近似中出现的极限的定量估计。

英文摘要:

We examine the stability of a class of quasilinear parabolic partial differential equations under perturbations. We are interested in the behavior of viscosity solutions as the perturbation parameter vanishes and establish explicit convergence rates by adapting standard comparison arguments. Despite the possible singular or degenerate nature of the parabolic operator, our framework covers, in particular, both the normalized and the variational $p$-parabolic equations, providing quantitative estimates for perturbations of the exponent $p$ and limits arising from regularized approximations.
