Alternating covariant tensor field 共變交錯(cuò)張量場(chǎng)
The more general case of a tensor field is similar but more complicated 較普遍的張量場(chǎng)情況大致相似,但是更為復(fù)雜。
Stress - energy tensor field 應(yīng)力能張量場(chǎng)
Witten ' s open string field theory formulate the interaction of bosonic open strings in the language of noncommutative geometry . compactification of matrix theory on the noncommutative torus was argued to correspond to supergravity with constant background three form tensor field . more generally , it has been realised that noncommutative gauge theory arises in the worldvolume theory on d - brane in the presence of a constant background b field in string theory Witten的開(kāi)弦場(chǎng)論用非對(duì)易幾何描述了玻色開(kāi)弦的相互作用;在非對(duì)易torus上的矩陣?yán)碚摰木o化對(duì)應(yīng)于帶有常數(shù)三形式張量場(chǎng)的超引力;更為普遍的,非對(duì)易規(guī)范理論可以自然地產(chǎn)生在帶有常數(shù)b背景場(chǎng)的三維d - brane上。
In mathematics, physics, and engineering, a tensor field assigns a tensor to each point of a mathematical space (typically a Euclidean space or manifold). Tensor fields are used in differential geometry, algebraic geometry, general relativity, in the analysis of stress and strain in materials, and in numerous applications in the physical sciences and engineering.
