Heisenberg群中具有粗糙核的非局部渗流方程

Nonlocal Filtration Equations with Rough Kernels in the Heisenberg Group

Rong Tang

摘要:

基于对$\mathbb{R}^n$上积分微分方程的广泛研究,我们考虑了Heisenberg群$\mathbb{H}^n$上具有粗糙核的非局部过滤型方程.我们证明了在适当的初值条件下,该方程的弱解的存在唯一性。进一步,我们得到了多孔介质型方程($m\geq 1$)解的大时间行为和变号解的一致Hölder正则性.注意,海森堡群$\mathbb{H}^n$上的共形分数算子$\mathscr{L}_{α/2}$和纯幂分数算子$\mathscr{L}^{α/2}$都有它们的具有合适核的整表示。因此,本文的所有结果对带有$\mathscr{L}_{α/2}$或$\mathscr{L}^{α/2}$算子的方程都成立.

英文摘要:

Motivated by the extensive investigations of integro-differential equations on $\mathbb{R}^n$, we consider nonlocal filtration type equations with rough kernels on the Heisenberg group $\mathbb{H}^n$. We prove the existence and uniqueness of weak solutions corresponding to suitable initial data. Furthermore, we obtain the large time behavior of solutions and the uniform Hölder regularity of sign-changing solutions for the porous medium type equations ($m\geq 1$). Notice that both conformal fractional operators $\mathscr{L}_{α/2}$ and pure power fractional operators $\mathscr{L}^{α/2}$ on the Heisenberg group $\mathbb{H}^n$ have their integral representations with suitable kernels. Therefore, all the results in this paper will hold for these equations with operators $\mathscr{L}_{α/2}$ or $\mathscr{L}^{α/2}$.
