摘要

In this paper, we discuss a posteriori error estimates of the eigenvalue λh given by Adini nonconforming finite element. We give an assymptotically exact error estimator of the λh. We prove that the order of convergence of the λh is just 2and the λh converge from below for sufficiently small h.
