The classical theory of such locally “anti-de Sitter” spaces is treated in an elementary way, using visualizable models.

Anti-de-Sitter Spacetime and Its Uses,This is a pedagogical account of some of the global properties of Antide- Sitter spacetime with a view to their application to the AdS/CFT correspondence. Particular care is taken over the distinction between Anti-de-Sitter and its covering space. It is argued that it is the former which is important.作者: 干旱 時間: 2025-3-26 16:15 作者: leniency 時間: 2025-3-26 17:40 作者: 颶風 時間: 2025-3-27 00:28
