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。 -
In this paper, the best contribution is to discover that the cofinalities of elements of minimal linearly compactification of go - space exactly reflect the properties of go - space. thus we can set up the relation between go - space and ordinals and resolve some problems which are not resolved by predecessors
但對go -空間的研究還有許多尚待解決的問題，本文的主要工作是發現了go -空間的最小線性序緊化中點的共尾數能很好的反映go空間的性質，從而把go -空間和序數聯系了起來，解決了前人遺留的一系列問題。 -
So a 5d fluid is introduced to balance the gravity from the two branes. and a class of exact bulk solutions is obtained. by requiring a 4d effective curvature to have a minimum, the compactification size of the extra dimension is discussed
為平衡兩個膜之間的引力，我們在bulk中引入了五維流體並得出了一族bulk精確解；由有效四維曲率的極小值條件，我們討論了額外維的緊致大小。 -
Reviewing exiting concepts and theories about agricultural supply chain, a classification criterion is presented, in consideration of complexity, of compactification, of reliability, and of optimization. based on existing eoq, a new two - stage model and its solution are given. this model takes into account the seasonal variety of products demand
本文首先回顧了有關農業供應鏈和農產品庫存的相關概念、庫存理論和農業庫存模型研究的現狀;分別從供應鏈的復雜度、供應鏈節點企業集中程度、供應鏈的可靠度和優化目標不同四個方面提出了供應鏈結構的分類標準。
