An equal-order mixed finite element for the time fractional nonlinear parabolic equations
In this paper,we propose a k-th equal-order mixed finite element for the numerical solutions of the time fractional nonlinear parabolic equations.To obtain the fully discrete scheme of finite element,the classi-cal L1 scheme is used in the time direction and the stabilized mixed finite element method based on local pro-jection is used in the spatial direction.We define the mixed projection and give the error estimate for the finite element.Numerical examples verify the theoretical results.
