| Research Abstract |
We showed that the lower-dimensional double-spinor(DS) superstring has such a physical spectrum that coincides with the pure-spinor superstring s but its Lorentz symmetry is anomalous. Duplicating the whole superspace co-ordinates, we constructed the DS superstring on the coset-superspace. Investigating the Killing spinor equations in the Heterotic supergravity for AdS3×M7 with fluxes, we classified M7 based on their G-structures and intrinsic torsions. The no-ghost theorem for Neveu-Schwarz string was directly proved in 0-picture. We explicitly fixed the gauge invariance of modified cubic open superstring theory and showed that the physical propagator has poles at the zeros of the Virasoro operator L0.
