Abstract
We have computed the sequence of memory functions (t) and their Laplace transforms, for the one-dimensional Ising model in a transverse field at T=∞. The form of these functions shows explicitly why the Mori continued-fraction approach, with traditional truncation schemes, fails for this model.
