Let $$\Omega$$ be a bounded $$C^2$$ domain in $${\mathbb {R}^{n}}$$ and $$u\in C({\mathbb {R}^{n}})$$ solves $$\begin{aligned} \begin{aligned} \Delta u + Iu C_0|Du| \ge -K\quad \text {in}\; \Omega , \quad - C_0|Du|\le K u=0\quad ^c, \end{aligned} \end{aligned}$$ the viscosity sense, where $$0\le a\le A_0$$ $$C_0, K\ge 0$$ I is suitable nonlocal operator. We show that $$u/\delta$$ $$C^{\upkappa ...
