Abstract: (Springer)
Conformal covariant Green's functions and operator-product expansions for more than two operators are discussed. Analyticity properties are investigated and asymptotic expressions derived. Extension inD-dimensional space-time is studied and the peculiar role ofD=2, both group-theoretically and as connected to infinite-momentum frames, is pointed out. The role of shadow singularities in relation to Euclidean metrics is discussed.- field theory: operator product
