abstract = "Abstract: For the heat equation on a rectangle, we consider the finite difference ADI method without a perturbation term on vertical sides for the intermediate solution. Using stability results of Andreev [1, 2] for the discrete harmonic function we prove, except for a $$\sqrt {\ln(1{\text{/}}h)} $$ factor, the second order bound that is stated without a proof by Samarski [8].",
