摘要：

We consider the reduction of supersymmetry in N-extended four-dimensional supergravity via the super-Higgs mechanism in theories without cosmological constant. We provide an analysis largely based on the properties of long and short multiplets of Poincare supersymmetry. Examples of the super-Higgs phenomenon are realized in spontaneously broken N = 8 supergravity through the Scherk-Schwarz mechanism and in superstring compactification in presence of brane fluxes. In many models the massive vectors count the difference in number of the translation isometrics of the scalar sigma-model geometries in the broken and unbroken phase.
