cond class constraints cannot be separated from the first class constraints in a Lorentz covariant way, and this greatly complicates any attempt at Lorentz covariant quantization, as it does for the GS superstring. 14 EFTA00614988 Intellectual Merit The goal of this project is to further the underst

string action exists only for spacetime dimensions D = 3,4,6,10. As for the RNS string, quantization of the light-cone gauge-fixed action preserves Lorentz invariance if D = 10 but not otherwise for D > 4. Recently, it was shown that the Lorentz invariance, and spacetime supersymmetry, of the superstrin

description in Bob's frame we make a pure boost, using (6) and (7). We note that, just as in special relativity, it is completely unambiguous what Lorentz transformation to use; this is fixed by the requirement that the origin of Bob's coordinates coincide with the origin of Alice's coordinates.
