Special Issue Information

Dear Colleagues,

In the last few decades, the application of fractional calculus to real-world problems has grown rapidly, with the use of dynamical systems described by fractional differential equations (FDEs) as one of the ways to understand complex materials and processes. Due to the ability to model the non-locality, memory, spatial heterogeneity and anomalous diffusion inherent in many real-world problems, the application of FDEs has been attracting much attention in many fields of science and is still under development. However, generally, the fractional mathematical models from science and engineering are so complex that analytical solutions are not available. Therefore, numerical solution has been an effective tool to deal with fractional mathematical models.

This Special Issue aims to promote communication between researchers and practitioners on the application of fractional calculus, present the latest development of fractional differential equations, report state-of-the-art and in-progress numerical methods and discuss future trends and challenges. We cordially invite you to contribute by submitting original research articles or comprehensive review papers. This Special Issue will cover the following topics, but these are not exhaustive:

  1. Mathematical modeling of fractional dynamic systems;
  2. Analytical or semi-analytical solution of fractional differential equations;
  3. Numerical methods to solve fractional differential equations, e.g.,  the finite difference method, the finite element method, the finite volume method, the spectral method, etc.;
  4. Fast algorithm for the time or space fractional derivative;
  5. Mathematical analysis for fractional problems and numerical analysis for the numerical scheme;
  6. Applications of fractional calculus in physics, biology, chemistry, finance, signal and image processing, hydrology, non-Newtonian fluids, etc.

In this work, a fully discrete mixed finite element (MFE) scheme is designed to solve the multi-term time-fractional reaction–diffusion equations with variable coefficients by using the well-known L1 formula and the Raviart–Thomas MFE space. The existence and uniqueness of the discrete solution is proved by using the matrix theory, and the unconditional stability is also discussed in detail. By introducing the mixed elliptic projection, the error estimates for the unknown variable u in the discrete L(L2(Ω)) norm and for the auxiliary variable λ in the discrete L((L2(Ω))2) and L(H(div,Ω)) norms are obtained. Finally, three numerical examples are given to demonstrate the theoretical results. Full article
