Existence, uniqueness, and approximation of solutions to some nonlinear diffusion problems

[摘要] We study the existence and approximation of a nontrivial positive solution for a nonlinear ordinary differential equation of second order. To prove the uniqueness of positive solutions, we use some estimates of the error between exact and approximate solutions. The equation arises in the study of some nonlinear diffusion problems.
