Abstract

We give a Lagrangian and display all local symmetries for the N=4 topological string of Berkovits, Vafa and Siegel, the latter previously known in the superconformal gauge. Leading to a small N=4 superconformal algebra and exhibiting the manifest Lorentz invariance the model is proposed to be a framework for restoring the Lorentz invariance in N=2 string scattering amplitudes.
