abstract = {<p style="text-align: justify;">In this paper, a robust modified weak Galerkin (MWG) finite element
method for reaction-diffusion equations is proposed and investigated. An advantage
of this method is that it can deal with the singularly perturbed reaction-diffusion
equations. Another advantage of this method is that it produces fewer degrees of
freedom than the traditional WG method by eliminating the element boundaries
freedom. It is worth pointing out that, in our method, the test functions space is the
same as the finite element space, which is helpful for the error analysis. Optimal-order error estimates are established for the corresponding numerical approximation
in various norms. Some numerical results are reported to confirm the theory.</p>},
