noun
anti-de Sitter space
A concept in theoretical physics, specifically a maximally symmetric vacuum solution of Einstein's field equations with a negative cosmological constant. Used in string theory and AdS/CFT correspondence.
反ドジッター空間は、負の宇宙定数を持つアインシュタイン方程式の解の一つである。
Anti-de Sitter space is one of the solutions to Einstein's equations with a negative cosmological constant.
De Sitter space has a positive cosmological constant, while anti-de Sitter space has a negative one.
From English 'anti-de Sitter space', named after the Dutch astronomer Willem de Sitter. The prefix 反 (anti-) is added to ドジッター空間 (de Sitter space).
