We consider the bilinear finite element method on a Shishkin mesh for the singularly perturbed elliptic boundary value problem ~2/a2u o2u-~ ~-{-~-] % a(z,y)u-f(z,y) in two space di-meusions. By using a very sophisticated asymptotic expansion of Han et al. [1] and the technique we used in [2], we prove that our method achieves almost second-order uniform(More)
