In physics, a gauge theory is a type of field theory in which the Lagrangian is invariant under a continuous group of local transformations.

3.
When the field is slowly - varying , the scalar field potential acts like a cosmological constant . in addition to the quintessence models , many other theories for dark energy have been proposed , including models based on super - symmetric gauge theories , super - gravity , small extra dimensions , large extra dimensions , quantum field theory effects in curved space - time . all these models are essentially based on the existence of a mass less scalar field acting at a cosmic scale 除了真空场模型外，科学家亦提出其他解释黑暗能量的理论，这些模型建基于不同的物理理论或假设，例如超对称规范理论超重力增加一些小或大的空间维数量子力学在弯曲时空的影响等等，这些理论模型，返本溯源，其实背后都假设存在著一个特性类似于宇宙常数的无质量纯量场。
4.
Abstract : based on the gauge theory of various interactions , some new solutions of the gauge field equations are discussed , the potential is introduced , and the relations among the results and limit cycle , various singular points are derived . finally , it is expounded that these results possess probably physical meaning on the property and phase transition of particles 文摘:从各种相互作用的规范理论出发，讨论了规范场方程的某些新的解，并引入了势，然后探讨了它们与极限环、各种奇异点的关系，最后论述了这些结果可能具有的粒子性质和相变等物理意义
5.
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的开弦场论用非对易几何描述了玻色开弦的相互作用；在非对易torus上的矩阵理论的紧化对应于带有常数三形式张量场的超引力；更为普遍的，非对易规范理论可以自然地产生在带有常数b背景场的三维d - brane上。
6.
In the first way , the coordinate become operaotrs acting on a hilbert space , which provides for a respresentation space of the noncommutative space , on the other hand , starting with the standard commutative gauge theory action and then reinterpreting any products of fields appearing in terms of the moyal product 从而非对易空间的场量是算子的函数。另一方面，我们可以从普通空间的规范理论的作用量出发，然后用moyal星乘积来代替普通空间的规范理论中场量的普通乘积。从而给出非对易空间规范理论的作用量。
