To solve such a type of problems, a Modified Initial Value Technique (MIVT) is proposed on an appropriate piecewise uniform Shishkin mesh. The MIVT is shown to be of second order convergent (up to a logarithmic factor). Numerical results are presented which are in agreement with the theoretical results.}, type={artykuł}, title={A robust computational technique for a system of singularly perturbed reaction-diffusion equations}, keywords={asymptotic expansion approximation, backward difference operator, trapezoidal method, piecewise uniform Shishkin mesh}, }
