The numerical resolution of shallow water equations (SWE) is required in many environmental problems involving free surface flow. Reduced-order models (ROMs) based on the POD allow such problems to be solved more efficiently in terms of computational

A singularly perturbed parabolic problem of convection-diffusion type with a discontinuous initial condition is examined. A particular complimentary error function is identified which matches the discontinuity in the initial condition. The difference

Pointwise accurate numerical methods are constructed and analysed for three classes of singularly perturbed first order transport problems. The methods involve piecewise-uniform Shishkin meshes and the numerical approximations are shown to be paramet

Numerical approximations to the solution of a linear singularly perturbed parabolic reaction-diffusion problem with incompatible boundary-initial data are generated. The method involves combining the computational solution of a classical finite diffe

A novel implementation of the reduced-order model (ROM) of 1D advection-diffusion equation by means of a modified Proper Orthogonal Decomposition (POD) method is presented. This modified method is based on a coordinate transformation (CT-POD) that al

The Riemann–Liouville–Caputo (RLC) derivative is a new class of derivative that is motivated by modelling considerations; it lies between the more familiar Riemann–Liouville and Caputo derivatives. The present paper studies a two-point boundary

A singularly perturbed parabolic problem of convection-diffusion type with a discontinuous initial condition is examined. An analytic function is identified which matches the discontinuity in the initial condition and also satisfies the homogenous pa

An initial–boundary value problem with a Riemann–Liouville-Caputo space fractional derivative of order α ∈ ( 1 , 2 ) is considered, where the boundary conditions are reflecting. A fractional Friedrichs’ inequality is derived and is used to p
