Abstract

We will discuss some properties of the pure spinor string on an AdS₅×S⁵ background. Using a classical Hamiltonian analysis we will show that the vertex operator for the massless state that is in the cohomology of the BRST charges describes on-shell fluctuations around an AdS₅×S⁵ background.
