Abstract [en]

In this thesis we present solutions of spontaneous compactifications of D=11, N=1 supergravity on parallelizable manifolds S^1, S^3 and S^7. In Freund-Rubin compactifications one usually obtains AdS vacua in 4D, these solutions usually sets the fermionic VEV's to zero. However giving them non zero VEV's allows us to define torsion given by the fermionic bilinears that essentially flattens the geometry giving us a vanishing cosmological constant on M_4. We further give an analysis of the consistent truncation of the bosonic sector of D=11 supergravity on a S^3 manifold and relate this to other known consistent truncation compactifications. We also consider the squashed S^7 where we check for surviving supersymmetries by analyzing the generalised holonomy, this compactification is of interest in phenomenology.
