Divergent ? complex amplitudes in two dimensional string theory

A bstract In a recent paper, Balthazar, Rodriguez and Yin found remarkable agreement between the one instanton contribution to scattering amplitudes of two dimensional string theory those in matrix model first subleading order. The comparison was carried out numerically by analytically continuing external energies imaginary values, since for real result diverges. We use insights from field give finite expressions energies. also show that parts computed this way reproduce full results general involving multiple closed strings.
