In this http://www.ulb.ac.be/sciences/ptm/pmif/Rencontres/specgeom.pdf, for example on p.7 and in many other references, people usually say:
we will concentrate on the bosonic part of the Lagrangian in N=1 (sometimes N=2) supergravity.
In other incidents, people say, that they are going to consider backgrounds that are considered having vanishing values of fermions, but why? Why do we have to consider bosonic backgrounds and not, for instance, fermionic backgrounds?
