文摘<正> From the k symmetric action of IIB string in AdS_2×S~2 background given by Zhou,we derive theequations of motion.By using the twisted dual transformation which was introduced by Hou,we construct the flatcurrents,conserving non-local charge with one free parameter,for the superstring in AdS_2×S_2.
