A Brief Comment on Instanton-like Singularities and Cosmological Horizons
arXiv:hep-th/0204119 · doi:10.1088/1126-6708/2003/01/010
Abstract
We argue that in the presence of instanton-like singularities, the existence of cosmological horizons can become frame-dependent, ie. a horizon which appears in Einstein frame may not appear in string frame. We speculate on the relation between instanton-like singularities and the formulation of quantum gravity in de Sitter space.
