On Boundary Layer Expansions for a Singularly Perturbed Problem with Confluent Fuchsian Singularities

We consider a family of nonlinear singularly perturbed PDEs whose coefficients involve a logarithmic dependence in time with confluent Fuchsian singularities that unfold an irregular singularity at the origin and rely on a single perturbation parameter. We exhibit two distinguished finite sets of ho...
