AI 中文摘要
我们通过适应于文献[Moosavi26]中投影拔河构造的逐点渐近均值恒等式，刻画了有界区域Ω⊂Rⁿ中正则化p-拉普拉斯方程div((1 + |Dv|²)^(p/2 - 1)Dv) = 0（1 < p < ∞）的解。对于v∈C²(Ω)，求解该方程等价于特定等式。还证明了p≥2时相关结论。
英文摘要
We characterize solutions of the regularized $p$-Laplace equation \[ \operatorname{div}\!\left((1+|Dv|^2)^{p/2-1}Dv\right)=0, \qquad 1<p<\infty, \] in a bounded domain $Ω\subset\mathbb{R}^n$ by a pointwise asymptotic mean value identity. For $v\in C^2(Ω)$, solving the equation is equivalent to \[ v(x) = \frac{\widetildeα}{2} \left( \mathcal{S}_{\varepsilon}^{+}[v](x) + \mathcal{S}_{\varepsilon}^{-}[v](x) \right) + \widetildeβ \int_{B_\varepsilon(0)} v(x+h)ρ_\varepsilon(h)\,dh + o(\varepsilon^2), \] where \[ \widetildeα = \frac{p-2}{p+n+1}, \qquad \widetildeβ = \frac{n+3}{p+n+1}. \] The kernel $ρ_\varepsilon$ is the semicircular marginal of normalized Lebesgue measure on the $(n+1)$-dimensional ball, and $\mathcal{S}_{\varepsilon}^{+}$ and $\mathcal{S}_{\varepsilon}^{-}$ are the tilted strategic functionals arising from the affine lift \[ w(x,s)=v(x)+s. \] The lifted gradient $(Dv,1)$ never vanishes, so the extremal second-order expansion is valid at every gradient regime. The characterization holds for the full range $1<p<\infty$. By standard interior regularity for nondegenerate regularized $p$-growth equations, weak solutions are smooth in the interior; the weak and viscosity viewpoints for related quasilinear $p$-Laplace equations are connected in \cite{JLM01}. The convergence of the associated projected dynamic programming scheme is established in the companion paper \cite{Moosavi26}.
