Applied N=1 supergravity

摘要: A review of recent developments in the applications N=1 supergravity to construction unified models elementary particle interactions is given. Couplings with matter consisting an arbitrary set left handed multiplets and a gauge multiplet are discussed. General formulation spontaneous symmetry breaking criteria for internal local supersymmetry described.
