An estimate of\(\mathop {\max }\limits_{\Omega '} |u_x^\varepsilon |\), Ω′⊃⊃Ω, for solutions uε of the family of equations $$ - \frac{d}{{dx_i }}\frac{{u_{x_i } }}{{\sqrt {1 + u_x^2 } }} - \varepsilon \Delta u + a(x,u,u_x ) = 0, x \in \Omega ,\varepsilon \in (0,1],$$ with a nondifferentiable lower term a is given. The majorant in the estimate depends on\(\mathop {\max }\limits_\Omega |u^\varepsilon |\) and the distance between Ω′ and ∂Ω, and does not depend on ε. This publication is related to [2, 3].
