"""In summary I think the early sections of the book give a very nice picture of the difficulties associated with singularly perturbed convection-diffusion problems. The insight gained from the structure of the uniform convergence proofs could be used to analyze different discretizations and mesh adaptations strategies. The extensive number of two-dimensional examples could also serve as a great source of benchmark solutions to test other approaches."" -SIAM Review vol. 43, no.3 (549-581)"
