HIDDEN SUPERSYMMETRY IN POHLMEYER-REDUCED FORM OF AdS_n × Sn SUPERSTRINGS

摘要

We review how the AdS_(2) × S~(2), AdS_(3) × S~(3) and AdS_(5) × S~(5) superstring theories in the Pohlmeyer-reduced form exhibit hidden , and worldsheet supersymmetries, with emphasis on the last two cases. Their characteristic feature is the presence of non-local terms in the supersymmetry transformations.
