Supersymmetry vacuum configurations in a d=11 supergravity
Volkov D. V. , Sorokin D. P. , Tkach V. I.
Some new supersymmetry vacuum configurations of a d — 11 supergravity, which are invariant under the group SO(3,2)xSU(3)xSU(2), are derived. The seven-dimensional compact space corresponding to these configurations is an SU(2) instanton on CP2.
