Abstract

The problem of a conformally covariant expansion of the four-point function is solved both in Minkowski and in Euclidean space. The role of shadow singularities is discussed. The expansion is examined for its analyticity properties and the various lightcone limits are performed. Vertex identities are derived in momentum space and simply interpreted.
