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 從而非對易空間的場量是算子的函數。另一方面,我們可以從普通空間的規范理論的作用量出發,然后用moyal星乘積來代替普通空間的規范理論中場量的普通乘積。從而給出非對易空間規范理論的作用量。

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的開弦場論用非對易幾何描述了玻色開弦的相互作用;在非對易torus上的矩陣理論的緊化對應于帶有常數三形式張量場的超引力;更為普遍的,非對易規范理論可以自然地產生在帶有常數b背景場的三維d - brane上。

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:從各種相互作用的規范理論出發,討論了規范場方程的某些新的解,并引入了勢,然后探討了它們與極限環、各種奇異點的關系,最后論述了這些結果可能具有的粒子性質和相變等物理意義

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 除了真空場模型外,科學家亦提出其他解釋黑暗能量的理論,這些模型建基于不同的物理理論或假設,例如超對稱規范理論超重力增加一些小或大的空間維數量子力學在彎曲時空的影響等等,這些理論模型,返本溯源,其實背后都假設存在著一個特性類似于宇宙常數的無質量純量場。

Lattice gauge theory 晶格規范理論

Noncommutative gauge theory are discribed via two equivalent descriptions 非對易規范理論有兩種等價的描述方法。
