title: Dual flows in hyperbolic space and de Sitter space creator: Yu, Hao subject: ddc-510 subject: 510 Mathematics description: We consider contracting flows in (n+1)-dimensional hyperbolic space and expanding flows in (n+1)-dimensional de Sitter space. When the flow hypersurfaces are strictly convex we relate the contracting hypersurfaces and the expanding hypersurfaces by the Gauß map. The contracting hypersurfaces shrink to a point in finite time while the expanding hypersurfaces converge to the maximal slice {\tau = 0}. After rescaling, by the same scale factor, the rescaled contracting hypersurfaces converge to a unit geodesic sphere, while the rescaled expanding hypersurfaces converge to slice {\tau = −1} exponentially fast. date: 2017 type: Dissertation type: info:eu-repo/semantics/doctoralThesis type: NonPeerReviewed format: application/pdf identifier: https://archiv.ub.uni-heidelberg.de/volltextserverhttps://archiv.ub.uni-heidelberg.de/volltextserver/23553/1/dissertation.pdf identifier: DOI:10.11588/heidok.00023553 identifier: urn:nbn:de:bsz:16-heidok-235538 identifier: Yu, Hao (2017) Dual flows in hyperbolic space and de Sitter space.
