Anti-de Sitter space is a term used in the field of theoretical physics and mathematics. It is a type of space that has a negative curvature, which is different from the positive curvature of the more commonly known de Sitter space. This article will provide a definition and meaning of anti-de Sitter space, as well as its origin, associations, synonyms, and antonyms.
Definitions
Anti-de Sitter space is a mathematical model of space-time that is characterized by a negative cosmological constant. It is a type of space that has a hyperbolic geometry, which means that its curvature is negative. This space is named after Willem de Sitter, a Dutch mathematician, and physicist, who was one of the pioneers in the study of the universe’s structure.
Origin
Anti-de Sitter space was first introduced in 1917 by a Dutch mathematician named Willem de Sitter. He used this space to describe the universe’s structure, which he believed to be static and infinite. Later, in the 1980s, anti-de Sitter space gained popularity in the field of theoretical physics, particularly in the study of string theory and its connection to gravity.
Meaning in different dictionaries
According to the Oxford English Dictionary, anti-de Sitter space is defined as “a space-time model with a negative cosmological constant that is used in the study of theoretical physics.” The Merriam-Webster Dictionary defines it as “a space-time with a negative cosmological constant that is used in the study of string theory.”
Associations
Anti-de Sitter space is associated with a variety of concepts in the field of theoretical physics, including string theory, black holes, and the holographic principle. It is also associated with the AdS/CFT correspondence, which is a conjecture that relates the physics of anti-de Sitter space to the physics of conformal field theory.
Synonyms
Some synonyms for anti-de Sitter space include hyperbolic space, negatively curved space, and AdS space.
Antonyms
The antonym of anti-de Sitter space is de Sitter space, which is a type of space that has a positive curvature.
The same root words
The root words of anti-de Sitter space are “anti-” and “de Sitter.” “Anti-” means against or opposite, while “de Sitter” refers to Willem de Sitter, the Dutch mathematician who first introduced this space.
