非齐次增长分式问题的全局正则性结果

Global regularity results for non-homogeneous growth fractional problems

Jacques Giacomoni, Deepak Kumar, K. Sreenadh

摘要:

本文研究了一类含分数阶$(p,q)$ -Laplacian算子的问题(记作$(-Δ)^{s_1}_{p}+(-Δ)^{s_2}_{q}$,其中$1<p,q<\infty$和$s_1,s_2\in (0,1)$)弱解的整体Hölder正则性.利用适当的Caccioppoli不等式和局部有界性结果证明了弱Harnack型不等式.因此,通过适当的迭代过程,我们建立了局部弱解的内部Hölder正则性,而不需要假设有界。我们证明的全局Hölder正则性结果将Giacomoni,Kumar和Sreenadh(arXiv:2102.06080)的正则性结果扩展和改进到次二次情况(即$q<2$)和更一般的右手边,这需要一种不同的新方法。此外,我们建立了一个关于弱解的非局部Harnack型不等式,它是独立有趣的.

英文摘要:

This article concerns with the global Hölder regularity of weak solutions to a class of problems involving the fractional $(p,q)$-Laplacian, denoted by $(-Δ)^{s_1}_{p}+(-Δ)^{s_2}_{q}$, for $1<p,q<\infty$ and $s_1,s_2\in (0,1)$. We use a suitable Caccioppoli inequality and local boundedness result in order to prove the weak Harnack type inequality. Consequently, by employing a suitable iteration process, we establish the interior Hölder regularity for local weak solutions, which need not be assumed bounded. The global Hölder regularity result we prove expands and improves the regularity results of Giacomoni, Kumar and Sreenadh (arXiv: 2102.06080) to the subquadratic case (that is, $q<2$) and more general right hand side, which requires a different and new approach. Moreover, we establish a nonlocal Harnack type inequality for weak solutions, which is of independent interest.
