Higher order gamma-limits for singularly perturbed Dirichlet-Neumann problems
A mixed Dirichlet-Neumann problem is regularized with a family of singularly perturbed Neumann-Robin boundary problems, parametrized by ε > 0. Using an asymptotic development by Gamma-convergence, the asymptotic...

A PRIORI DIFFUSION-UNIFORM ERROR ESTIMATES FOR SINGULARLY PERTURBED PROBLEMS: MIDPOINT-DG DISCRETIZATION
We deal with a nonstationary semilinear singularly perturbed convection diffusion problem. We discretize this problem by discontinuous Galerkin method in space and by midpoint rule in time. We present diffusion uni...

A Note on Preconditioning for Singularly Perturbed Problems Discretized by Wavelets
In the modeling of boundary value problems for singularly perturbed differential equations, one can observe boundary and interior layers whose width can be arbitrary small. To solve such types of problems a lot of ...

A simple approach to reliable and robust a posteriori error estimation for singularly perturbed problems
A simple flux reconstruction for finite element solutions of reaction-diffusion problems is shown to yield fully computable upper bounds on the energy norm of error in an approximation of singularly perturbed reaction-diffu...

Optimal error estimates for nonstationary singularly perturbed problems for low discretization orders
Nonstationary 1D singularly perturbed convection-diffusion equation is discretized in space by the finite element method on a Shishkin mesh and by time discontinuous Galerkin method. The resulting scheme is analyzed and diffusion-un...
