The pre-inflationary evolution of the universe describes the beginning of the\nexpansion from a static initial state, such that the Hubble parameter is\ninitially zero, but increases to an asymptotic constant value, in which it\ncould achieve a de Sitter (inflationary) expansion. The expansion is driven by\na background phantom field. The back-reaction effects at this moment should\ndescribe vacuum geometrical excitations, which are studied with detail in this\nwork using Relativistic Quantum Geometry.\n
