abstract = {<p style="text-align: justify;">A singularly perturbed parabolic equation of convection-diffusion
type with an interior layer in the initial condition is studied. The solution
is decomposed into a discontinuous regular component, a continuous outflow
boundary layer component and a discontinuous interior layer component. A
priori parameter-explicit bounds are derived on the derivatives of these three
components. Based on these bounds, a parameter-uniform Shishkin mesh is
constructed for this problem. Numerical analysis is presented for the associated
numerical method, which concludes by showing that the numerical method is
a parameter-uniform numerical method. Numerical results are presented to
illustrate the theoretical bounds on the error established in the paper.</p>},
