Query: Fully computable a posteriori error estimator using anisotropic flux
  equilibration on anisotropic meshes   Fully computable a posteriori error estimates in the energy norm are given
for singularly perturbed semilinear reaction-diffusion equations posed in
polygonal domains. Linear finite elements are considered on anisotropic
triangulations. To deal with the latter, we employ anisotropic quadrature and
explicit anisotropic flux reconstruction. Prior to the flux equilibration,
divergence-free corrections are introduced for pairs of anisotropic triangles
sharing a short edge. We also give an upper bound for the resulting estimator,
in which the error constants are independent of the diameters and the aspect
ratios of mesh elements, and of the small perturbation parameter.
