Abstract: The symmetrized dilogarithm L(x) satisfies certain identities containing an arbitrary number, denoted by n−3, of independent variables. It is shown that the general prescription for writing the (n − 3)-variable dilogarithm identity is closely related to that for writing the basic quantities in the n-point Veneziano amplitude of the dual resonance model, which is a physically unsuccessful model of strong interactions in particle physics. Duality transformations of n-point tree Feynman graphs of the ϕ3 theory are represented by birational transformations of n − 3 variables corresponding to the n − 3 internal lines of the tree and then the dilogarithm identities are expressed in terms of those variables. The identities can also be rewritten in a form independent of the choice of a particular tree by introducing three redundant parameters.
