The moduli space of CP1 stringy cosmic lumps

摘要

We examine the low-energy dynamics of CP1 lumps coupled to gravity. taking into account the gravitational back-reaction of the spacetime geometry. We show that the single lump moduli space is equipped with a three-dimensional metric, and we derive stability bounds on the scalar coupling constant. We also derive an expression for the multi-lump moduli space metric. (C) 2002 Published by Elsevier Science B.V. References: 17
