The Convex Hull of Two Circles in ,,rojective space, their algebraic boundary contains an irrational ruled surface of degree eight whose ruling forms a genus one curve. We classify which curves arise, classify the face lattices of the convex hulls, and determine which are spectrahedra. We also discuss an approach to these convex hulls using projective duality.作者: Gerontology 時(shí)間: 2025-3-22 13:22 作者: Gerontology 時(shí)間: 2025-3-22 17:37 作者: 樸素 時(shí)間: 2025-3-22 23:30 作者: Canopy 時(shí)間: 2025-3-23 02:39 作者: 禍害隱伏 時(shí)間: 2025-3-23 05:35
