Spacetime Superalgebra in AdS4 × S7 via Supermembrane Probe
Kazuyuki Furuuchi, Nobuyoshi Ohta, Jian-Ge Zhou
Abstract
The spacetime superalgebra via the supermembrane probe in the background of AdS4 × S7 is discussed to the lowest order in the spinor coordinate . To obtain the correct spacetime superalgebras, all 2 order corrections for supervielbein and super 3-form gauge potential have to be included. The central extension of the superalgebra OSp(8|4) of the super isometries for AdS4 × S7 is found.
