On Nonnegativity Preservation in Finite Element Methods for Subdiffusion Equations
Bangti Jin, Raytcho Lazarov, Vidar Thomée +1
We consider three types of subdiffusion models, namely single-term, multi-term and distributed order fractional diffusion equations, for which the maximum-principle holds and which…

Some error estimates for the finite volume element method for a parabolic problem
P. Chatzipantelidis, R. D. Lazarov, V. Thomee
We study spatially semidiscrete and fully discrete finite volume element methods for the homogeneous heat equation with homogeneous Dirichlet boundary conditions and derive error e…

Iterative methods for shifted positive definite linear systems and time discretization of the heat equation
William McLean, Vidar Thomée
In earlier work we have studied a method for discretization in time of a parabolic problem which consists in representing the exact solution as an integral in the complex plane and…
