【 摘 要 】

This article resumes recent advances in the development of a formalism that allows the incorporation of a hypothetical spontaneous reduction or collapse of wave function of matter fields within the context of semiclassical gravity. The proposal is applied to the inflationary scenario for the emergence of the primordial inhomogeneities and anisotropies out of the initially homogeneous and isotropic quantum state, to which, the early stages of inflation are supposed to drive the universe. In previous works we have argued that a scheme of this kind is required if we want to satisfactorily account for the emergence of the seeds of cosmic structure.
