An average effect of many tiny holes in nonlinear boundary value problems with monotone boundary conditions
\textit{H. Attouch} [Variational convergence of functions and operators (1984; Zbl 0561.49012)] has investigated the magnitude effect of many tiny holes, whose shapes are not spherical in general, to the potential term of the Dirichlet problem for the Laplace equation using the notion of capacity. The author extends this method to a different type of boundary conditions, replacing capacity by a different class of magnitude.
