{"arxiv_id":"hep-th/0602107","title":"Time Dependent Cosmologies and Their Duals","abstract":"We construct a family of solutions in IIB supergravity theory. These are time dependent or depend on a light-like coordinate and can be thought of as deformations of AdS_5 x S^5. Several of the solutions have singularities. The light-like solutions preserve 8 supersymmetries. We argue that these solutions are dual to the N=4 gauge theory in a 3+1 dimensional spacetime with a metric and a gauge coupling that is varying with time or the light-like direction respectively. This identification allows us to map the question of singularity resolution to the dual gauge theory.","primary_cat":"hep-th","cross_cats":[],"submitted_at":"2006-02-10T20:08:23+00:00","latest_version":3,"source":"arxiv","source_label":"arXiv","source_url":null,"has_pdf":true,"has_source":false,"verdict":"CONDITIONAL","confidence":"MODERATE","one_line_summary":"A family of time-dependent and light-like type IIB supergravity solutions is constructed and proposed to be dual to N=4 gauge theory in a spacetime with a varying metric and gauge coupling.","novelty_score":4.0,"correctness_risk":"medium","formal_verification":"none","upvotes":0,"downvotes":0,"pith_score":0,"inbound_count":22,"_links":{"html":"https://pith.science/paper/hep-th/0602107","verdict":"/api/v1/verdicts/hep-th/0602107"}}
