Subdiffusion with a time-dependent coefficient: Analysis and numerical solution [PDF]
Mathematics of Computation, 2018 In this work, a complete error analysis is presented for fully discrete solutions of the subdiffusion equation with a time-dependent diffusion coefficient, obtained by the Galerkin finite element method with conforming piecewise linear finite elements in

Numerical analysis of the wave propagation in a composite medium
Mathematical Modelling and Analysis, 2006 We consider the wave propagation process in a 2‐dimensional material structure composed of random oriented orthotropic crystals and analyse numerical results for the diffraction problem and the problem of waves interaction with a free boundary.

On the aposteriori error estimates for finite‐element solutions
Mathematical Modelling and Analysis, 1998 The analysis of the accuracy of the aposteriori error estimation procedure for finite‐element solutions is presented. The function Y — y is used as an aposteriori error estimator, here y ∈ S 0 1,Δ is the finite‐element solution of the given problem and Y
