THE CHARACTERISTIC DIFFERENCE METHOD FOR NONLINEAR CONVECTION-DIFFUSION PROBLEMS IN TWO SPACE VARIABLES
二维非线性对流-扩散方程的特征-差分解法

The characteristic difference method for nonlinear convection-diffusion problems in two space variables is considered in this paper. The characteristic difference schemes based on quadratic triangular or rectangular interpolation are established and the error estimates of these schemes are given.
