Let $\mathcal{N}_{mn}^{rs}$ be the Neumann coefficients introduced for the three-string vertex in the pp-wave background, and let $\lambda$ be the deformation parameter in the full…

Let the Neumann coefficients be the coefficients defining the three-string vertex of light-cone string field theory in a maximally supersymmetric pp-wave background, expanded in th…
