Error analysis of a FVEM for fractional order evolution equations with nonsmooth initial data
Error analysis of a FVEM for fractional order evolution equations with nonsmooth initial data
In this paper, a finite volume element (FVE) method is considered for spatial approximations of time fractional diffusion equations involving a Riemann-Liouville fractional derivative of order α ∈ (0, 1) in time. Improving upon earlier results [Karaa et al. , IMA J. Numer. Anal. 37 (2017) 945–964], error estimates in …
