Spacetime Topology Change: The Physics of Calabi-Yau Moduli Space
P. S. Aspinwall, B. R. Greene, D. R. Morrison
Abstract
We review recent work which has significantly sharpened our geometric understanding and interpretation of the moduli space of certain N=2 superconformal field theories. This has resolved some important issues in mirror symmetry and has also established that string theory admits physically smooth processes which can result in a change in topology of the spatial universe.
