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 id_scheme: DOI id_number: 10.11588/heidok.00023553 ppn_swb: 1656457822 own_urn: urn:nbn:de:bsz:16-heidok-235538 date_accepted: 2017-05-05 advisor: HASH(0x561a6282cab8) language: eng bibsort: YUHAODUALFLOWSI2017 full_text_status: public citation: Yu, Hao (2017) Dual flows in hyperbolic space and de Sitter space.
