A Brief Comment on Instanton-like Singularities and Cosmological Horizons | | Jason Kumar
; | | Date: |
15 Apr 2002 | | Journal: | JHEP 0301 (2003) 010 | | Subject: | hep-th | | 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. | | Source: | arXiv, hep-th/0204119 | | Services: | Forum | Review | PDF | Favorites | |
