Abstract: This thesis is concerned with iterative and monotone methods for numerical solutions of nonlinear elliptic boundary value problems. The methods we study here are called block iterative methods, which solve the nonlinear elliptic problems in twodimensional domain in R2 or higher dimensional domain in Rn. In these methods the nonlinear boundary value problem is discretized by the finite difference method. Two iteration processes, block Jacobi and block Gauss-Seidel monotone iterations, are investigated for computation of solutions of finite difference system using either an upper solution or a lower solution as the initial iteration. The numerical examples are presented for both linear and nonlinear problems, and for both block and pointwise methods. The numerical results are compared and discussed.
