A hybrid approach for singularly perturbed parabolic problem with discontinuous data
Nirmali Roy, Anuradha Jha
In this article, we study a two-dimensional singularly perturbed parabolic equation of the convection-diffusion type, characterized by discontinuities in the source term and convec…
A parameter uniform hybrid approach for singularly perturbed two-parameter parabolic problem with discontinuous data
Nirmali Roy, Anuradha Jha
In this article, we address singularly perturbed two-parameter parabolic problem of the reaction-convection-diffusion type in two dimensions. These problems exhibit discontinuities…
A parameter uniform method for two-parameter singularly perturbed boundary value problems with discontinuous data
Nirmali Roy, Anuradha Jha
A two-parameter singularly perturbed problem with discontinuous source and convection coefficient is considered in one dimension. Both convection coefficient and source term are di…
Parameter uniform numerical method for singularly perturbed two parameter parabolic problem with discontinuous convection coefficient and source term
Nirmali Roy, Anuradha Jha
In this article, we have considered a time-dependent two-parameter singularly perturbed parabolic problem with discontinuous convection coefficient and source term. The problem con…
