论文摘要
本文涉及非差异形式的分数$ p $ -laplace运算符$δ_p^s $,该形式已在[Bjorland,Caffarelli,Figalli(2012)]中引入。对于[2,\ infty)$和$ s \ in(\ frac {1} {2},1)$的任何$ p \,我们首先定义了两个非现代,非线性平均运算符的家族,由$ε$参数为参数,并定义为所有有界的,borel函数$:borel unction $:\ mathbbbbbbbb {r} $ {r} $ {r} $ {r} $ {r}。我们证明,$Δ_p^s u(x)$以$ε^{2S} $ - 订单系数在扩展每个$ε$ -A-平均值$ u(x)$的偏差时,在平均耗尽$ \ mathbb {r} r} r}^n $ $ $ $ $的范围的范围内,以$ \ \ to $^$^0 $ 0. Second, we consider the $ε$-dynamic programming principles modeled on the first average, and show that their solutions converge uniformly as $ε\to 0$, to viscosity solutions of the homogeneous non-local Dirichlet problem for $Δ_p^s$, when posed in a domain $\mathcal{D}$ that satisfies the external cone condition and subject to bounded, uniformly continuous data on $ \ mathbb {r}^n \ setMinus \ mathcal {d} $。 最后,我们将这种$ε$ appprotating解决方案解释为具有噪音的非本地拖船游戏的值。在此游戏中,玩家选择方向,而游戏位置则在与指定方向保持一致的无限锥体内随机更新,其光圈角依赖于$ p $和$ n $,并且已删除了$ε$ -TIP。
This paper concerns the fractional $p$-Laplace operator $Δ_p^s$ in non-divergence form, which has been introduced in [Bjorland, Caffarelli, Figalli (2012)]. For any $p\in [2,\infty)$ and $s\in (\frac{1}{2},1)$ we first define two families of non-local, non-linear averaging operators, parametrised by $ε$ and defined for all bounded, Borel functions $u:\mathbb{R}^N\to \mathbb{R}$. We prove that $Δ_p^s u(x)$ emerges as the $ε^{2s}$-order coefficient in the expansion of the deviation of each $ε$-average from the value $u(x)$, in the limit of the domain of averaging exhausting an appropriate cone in $\mathbb{R}^N$ at the rate $ε\to 0$. Second, we consider the $ε$-dynamic programming principles modeled on the first average, and show that their solutions converge uniformly as $ε\to 0$, to viscosity solutions of the homogeneous non-local Dirichlet problem for $Δ_p^s$, when posed in a domain $\mathcal{D}$ that satisfies the external cone condition and subject to bounded, uniformly continuous data on $\mathbb{R}^N\setminus \mathcal{D}$. Finally, we interpret such $ε$-approximating solutions as values to the non-local Tug-of-War game with noise. In this game, players choose directions while the game position is updated randomly within the infinite cone that aligns with the specified direction, whose aperture angle depends on $p$ and $N$, and whose $ε$-tip has been removed.
