摘要:

本文建立了一类双退化发展偏微分方程有界解的局部Hölder正则性估计。利用内标度技术和几何切向方法,我们得到了这类模型的尖锐的正则性估计,它只依赖于问题的泛参数和相容参数。在这样的情况下,我们的结果是自然的改进,通过一个统一的方法,在非线性演化的背景下退化结构的偏微分方程。作为我们的研究结果和方法的结果,我们解决了一个刘维型的结果与冻结系数和渐近估计在一定的近似制度,这可能有自己的数学兴趣的相关齐次问题的整体解决方案。我们还提供了明确的退化偏微分方程的例子,我们的结果发生。

英文摘要:

In this manuscript we establish local Hölder regularity estimates for bounded solutions of a certain class of doubly degenerate evolution PDEs. By making use of intrinsic scaling techniques and geometric tangential methods, we derive sharp regularity estimates for such models, which depend only on universal and compatibility parameters of the problem. In such a scenario, our results are natural improvements for former ones in the context of nonlinear evolution PDEs with degenerate structure via a unified approach. As a consequence for our findings and approach, we address a Liouville type result for entire solutions of a related homogeneous problem with frozen coefficients and asymptotic estimates under a certain approximating regime, which may have their own mathematical interest. We also deliver explicit examples of degenerate PDEs where our results take place.
