Webcontinuations of the Schwinger functions. For free eld theories these are all determined by the 2-point functions W 2 or S 2. The Wightman function W 2 is Poincar e-covariant, while the Schwinger function S 2 is Euclidean-covariant. This simple relation between the Minkowski and Euclidean space-time free eld theories masks a much more subtle ...
