Characteristic Nonconforming Finite Element Method For A Nonlinear Diffusion Dynamics Model With Age-structured Population

The paper focuses on age-dependent dynamical systems of nonlinear diffusion problem noncon-forming characteristics finite element method. This article discusses the nonlinear diffusion population dynamics model,we use a finite different method along the characteristic age-time direction combined with finite elements in the spatial variable.Using the nonconforming and the elliptic projection the accuracy error is obtained the same as the conforming finite element is fulling discrete scheme.
