Universality in the algebra of vertex strengths as generated by bilocal currents
Abstract
We review the derivation of the algebra of vertex strengths (AVS) from the algebra of current bilocals on the null plane in the deep Regge scaling region (DRSR). We discuss the difficulties and present a mathematical procedure yielding AVS through a smooth removal of the divergent ω ^{α} dependences which differ on both sides of the infinite "ωlocal" algebra of scaling functions. We suggest that the S_{a} charges in AVS (the 2 ^{++} trajectories' vertex strengths) may be given by the antisymmetrized matrix elements of the vector bilocals.
