We prove a posteriori error estimates of optimal order for linear
Schrödinger-type equations in the L∞(L2)- and the
L∞(H1)-norm. We discretize only in time by the
Crank-Nicolson method. The direct use of the reconstruction
technique, as it has been proposed by Akrivis et al. in [Math. Comput.75 (2006) 511–531], leads to a posteriori upper bounds that
are of optimal order in the L∞(L2)-norm, but of
suboptimal order in the L∞(H1)-norm. The optimality in
the case of L∞(H1)-norm is recovered by using an
auxiliary initial- and boundary-value problem.
