摘要

It is shown that for a certain class of Feynman graphs the singularity manifold as given by the Landau equations can be parameterized in a form very similar to Jost DANAD. In particular for n=4, the boundary to this perturbation singularity domain is shown to be precisely the p-space DANAD called (DANAD)'. The relationship between (DANAD)' and DANAD is a precise generalization of the relationship which exists between Kallen-Wightman Fkl andnFkl surfaces for the 5-point function case. In particular, the present result implies that the envelope of holomorphy of the union of permuted tubes cannot be continued beyond (DANAD). Since (DANAD) defines a natural domain of holomorphy, it Is very suggestive that (DANAD) might very well turn out to be part of the envelope of holomorphy.
