Ward identities and the vanishing theorem for loop amplitudes of the closed N=2 string
Klaus Junemann, Olaf Lechtenfeld
The existence of a ground ring of ghost number zero operators in the chiral BRST cohomology of the N=2 string is used to derive an infinite set of Ward identities for the closed-st…

Non-local symmetries of the closed N=2 string
Klaus Junemann, Olaf Lechtenfeld, Alexander D. Popov
By carefully analysing the picture-dependence of the BRST cohomology an infinite set of symmetry charges of the closed N=2 string is identified. The transformation laws of the phys…
