More on Penrose limit of AdS4×Q1,1,1

We consider a Penrose limit of AdS4×Q1,1,1 that provides the pp-wave geometry equal to the one in the Penrose limit of AdS4×S7. We expect that there exists a subsector of three-dimensional N=2 dual gauge theory which has enhanced N=8 maximal supersymmetry. We identify operators in the N=2 gauge theory with 11-dimensional supergravity KK excitations in the pp-wave geometry and describe how both the chiral multiplets and semi-conserved multiplets fall into N=8 supermultiplets.
