具有一般梯度增长的各向异性椭圆型问题解的存在性和精确估计

Sharp estimates and existence for anisotropic elliptic problems with general growth in the gradient

Francesco Della Pietra, Nunzia Gavitone

摘要:

本文证明了低阶项依赖于梯度的各向异性非线性椭圆问题解的精确估计和存在性结果。我们的原型是:$ \left\{ \begin{array}{ll} -\mathcal Q_{p}u =[H(Du)]^{q}+f(x) &\text{in }Ω,\\ u=0&\text{on }\partialΩ. \end{array} \right. $这里$Ω$是$\mathbb R^{N}$、$N\ge 2$、$0<p-1<q\le p<N$的有界开集,$\mathcal Q_{p}$是各向异性算子$ \mathcal Q_{p} u ={\rm div}\left( [H(Du)]^{p-1}H_ξ(Du) \right)$,其中$H$是$\mathbb R^{N}$的合适范数。此外,$f$属于适当的Marcinkiewicz空间。

英文摘要:

In this paper, we prove sharp estimates and existence results for anisotropic nonlinear elliptic problems with lower order terms depending on the gradient. Our prototype is: $ \left\{ \begin{array}{ll} -\mathcal Q_{p}u =[H(Du)]^{q}+f(x) &\text{in }Ω,\\ u=0&\text{on }\partialΩ. \end{array} \right. $ Here $Ω$ is a bounded open set of $\mathbb R^{N}$, $N\ge 2$, $0<p-1<q\le p<N$, and $\mathcal Q_{p}$ is the anisotropic operator $ \mathcal Q_{p} u ={\rm div}\left( [H(Du)]^{p-1}H_ξ(Du) \right)$, where $H$ is a suitable norm of $\mathbb R^{N}$. Moreover, $f$ belongs to an appropriate Marcinkiewicz space.
