We pursue the construction of higher-spin theory in AdS_4 from CFT_3 of the O(N) vector model in terms of canonical collective fields. In null plane quantization the coordinates of the AdS_4 space-time are generated from the collective coordinates...

In recent years holography has emerged as a powerful tool to study non-equilibrium phenomena in certain quantum theories, mapping challenging quantum dynamics onto the classical dynamics of gravitational fields in one higher dimension. One...

The pure spinor formalism is an alternative formulation of superstring theory which -- unlike the Ramond Neveu-Schwarz- and Green Schwarz frameworks -- maintains manifest Super Poincare symmetry in all steps of amplitude computations. I will first...
