 By Hölder and Sobolev inequalities, for $0 \le {\delta}\le 0$, [$$\begin{split}  |I_0+I_0| &\le C{\| {{\nabla}}\zeta \|}_\infty \cdot {\| u\zeta \|}_{0}^{\delta}\cdot {\| |u|^{0-{\delta}}+|p-c|\cdot|u|^{0-{\delta}} \|}_{\frac0{0-{\delta}/0},A_R}\\ &\le C ({\sigma}R)^{-0} {\| {{\nabla}}(u\zeta) \|}_{0}^{\delta}\cdot {\left( {\| u \|}_{q}^0+  {\| p-c \|}_{q/0
