@article{Roy2022ParameterUN, title={Parameter uniform numerical method for singularly perturbed two parameter parabolic problem with discontinuous convection coefficient and source term}, author={Nirmali Roy and Anuradha Jha}, journal={ArXiv}, year={2022}, volume={abs/2208.04109} }

In this article, we have considered a time-dependent two-parameter singularly perturbed parabolic problem with discontinuous convection coeﬃcient and source term. The problem contains the parameters (cid:15) and µ multiplying the diﬀusion and convection coeﬃcients, respectively. A boundary layer develops on both sides of the boundaries as a result of these parameters. An interior layer forms near the point of discontinuity due to the discontinuity in the convection and source term. The width of…
