  • High Accuracy Fitted Operator Methods for Solving Interior Layer Problems 

    Sayi, Mbani T (University of the Western Cape, 2020)
    Fitted operator finite difference methods (FOFDMs) for singularly perturbed problems have been explored for the last three decades. The construction of these numerical schemes is based on introducing a fitting factor ...

  • Higher order numerical methods for singular perturbation problems 

    Munyakazi, Justin Bazimaziki (University of the Western Cape, 2009)
    In recent years, there has been a great interest towards the higher order numerical methods for singularly perturbed problems. As compared to their lower order counterparts, they provide better accuracy with fewer mesh ...
