A Boundary-Layer Preconditioner for Singularly Perturbed Convection Diffusion
Scott P. MacLachlan, Niall Madden, Thái Anh Nhan
Motivated by a wide range of real-world problems whose solutions exhibit boundary and interior layers, the numerical analysis of discretizations of singularly perturbed differentia…

Uniform convergence on a Bakhvalov-type mesh using the preconditioning approach: Technical report
Thái Anh Nhan, Relja Vulanović
The linear singularly perturbed convection-diffusion problem in one dimension is considered and its discretization on a Bakhvalov-type mesh is analyzed. The preconditioning techniq…

Cholesky factorisation of linear systems coming from finite difference approximations of singularly perturbed problems
Thái Anh Nhan, Niall Madden
We consider the solution of large linear systems of equations that arise when two-dimensional singularly perturbed reaction-diffusion equations are discretized. Standard methods fo…
