$N$ -widths for singularly perturbed problems

Mathematica Bohemica

Kolmogorov $N$ -widths are an approximation theory concept that, for a given problem, yields information about the optimal rate of convergence attainable by any numerical method applied to that problem. We survey sharp bounds recently obtained for the $N$ -widths of certain singularly perturbed convection-diffusion and reaction-diffusion boundary value problems.
