We investigate the holographic correspondence between (p + 1)-dimensional (0 less than or equal to p less than or equal to 4) SYM theories with 16 supercharges and superstring theories on the near-horizon limit of Dp-brane backgrounds. We take an ...
We re-examine physical state representations in the covariant quantization of bosonic string. We especially consider one parameter family of gauge fixing conditions for the residual gauge symmetry due to null states (or BRST exact states), and obt...
