Descripción
Recent progress in understanding AdS_4/CFT_3 correspondence has requested the knowledge of an explicit form of the superstring action in type IIA superbackground whose bosonic subspace is AdS_4 X CP^3. We show how the required AdS_4\times CP^3 superspace with 32 fermionic directions can be obtained by the dimensional reduction of the D=11 AdS_4 X S^7 superspace.
