DDF amplitudes are lightcone amplitudes and the naturalness of Mandelstam map
Dripto Biswas, Igor Pesando
We show that on shell DDF amplitudes are on shell lightcone amplitudes and that Mandelstam maps emerge naturally with a precise normalization and are intrinsic to the DDF states. O…

Framed DDF operators and the general solution to Virasoro constraints
Dripto Biswas, Igor Pesando
We define the framed DDF operators by introducing the concept of local frames in the usual formulation of DDF operators. In doing so it is possible to completely decouple the DDF o…
