Abstract: The structure of topological charge fluctuations in the QCD vacuum is strongly restricted by the spectral negativity of the Euclidean 2-point correlator for $xeq0$ and the presence of a positive contact term. Some examples are considered which illustrate the physical origin of these properties.
