Jw. Barrett et Jf. Blowey, AN ERROR BOUND FOR THE FINITE-ELEMENT APPROXIMATION OF THE CAHN-HILLIARD EQUATION WITH LOGARITHMIC FREE-ENERGY, Numerische Mathematik, 72(1), 1995, pp. 1-20
An error bound is proved for a fully practical piecewise linear finite
element approximation, using a backward Euler time discretization, of
the Cahn-Hilliard equation with a logarithmic free energy.
