Предлагаются два итерационных метода решения нелинейной задачи Неймана \[Lu:=\sum_{i,j=1}^N\frac{\partial}{\partial x_i}(a_{ij}\frac{\partial u}{\partial x_j})=f(x,u,D_u^{\alpha}), x\in \Omega,\quad (1)\] \[\frac{\partial u}{\partial \sigma}:=\sum_{i,j=1}^Na_{ij}\frac{\partial u}{\partial x_i}cos(n,...
