. In this article, we have studied the convergence behavior of the Dirichlet-Neumann waveform re- laxation algorithms for time-fractional sub-diffusion and diffusion wave equations in 1D & 2D for regular domains, where the dimensionless diffusion coefficient takes different constant values in different subdomains. From numeri- cal experiments, we first capture the optimal relaxation parameters. Using these optimal relaxation parameters, our analysis estimates the rate of change of the convergence…

Dirichlet–Neumann waveform relaxation methods for parabolic and hyperbolic problems in multiple subdomains

A new waveform relaxation variant of the Dirichlet–Neumann algorithm is introduced for general parabolic problems as well as for the second-order wave equation for decompositions with multiple subdomains and its convergence behaviour is compared with classical and optimized Schwarz Waveform Relaxation methods.

Existence of a unique weak solution to a non-autonomous time-fractional diffusion equation with space-dependent variable order

In this contribution, we investigate an initial-boundary value problem for a fractional diffusion equation with Caputo fractional derivative of space-dependent variable order where the coefficients

Anomalous diffusion and transport in heterogeneous systems separated by a membrane

A rich variety of behaviours for the particle distribution at the interface and in the bulk may be found, depending on the choice of characteristic times in the boundary conditions and on the fractional index of the modelling equations.
