de sitter space
解釋
德西特空間-
Semi - symmetric spacelike hypersurfaces in de sitter space
空間中半對稱的類空超曲面 -
Compact maximal spacelike submanifolds in a de sitter space
空間中的緊致極大類空子流形 -
Just as the boundary of the escher print is a circle, the boundary of four - dimensional anti - de sitter space at any moment in time is a sphere
就如同艾雪版畫的邊界是個圓,四維反德西特空間的邊界在任何時刻都是個二維的球。 -
A crucial aspect of anti - de sitter space is that it has a boundary where time is well defined
反德西特時空的一個特殊性質是它有個邊界,邊界上還有明確的時間軸。 -
This paper contains three chapters. we discuss the pinching problems on the length of the second fundamental form of compact space - like submanifolds mn with unit parallel mean curvature vector in the de sitter space spn + p. in particular, a sufficient condition for mn with constant scalar curvature to be totally umbilical is given
討論desitter空間s _ p ~ ( n + p )中具有平行的單位平均曲率向量的緊致類空子流形m ~ n的第二基本形式長度拼擠問題,給出了具有常數量曲率的這種子流形是全臍球面的一個充分條件。 -
Anti - de sitter space, although it is infinite, has a “ boundary, ” located out at infinity
反德西特空間雖然無窮大,卻有個位於無窮遠的「邊界」 。 -
For four - dimensional anti - de sitter space, the boundary has two space dimensions and one time dimension
對於四維的反德西特空間來說,邊界則是三維的,其中兩維是空間,一維是時間。 -
In particular, does anything similar hold for a universe like ours in place of the anti - de sitter space
尤其是類似的概念是否在和我們這個世界相似的宇宙中也成立,而不是僅出現在反德西特空間中?
