我们研究膜的配置,产生大N规范理论与八个超对称性和超多重态。这些构形包括各种缠绕的、分数的和拉伸的膜或弦。我们所研究的相应时空几何有一种独特的奇异性,称为斥力。我们发现,这种奇异性是由一个独特的机制,离开一个光滑的几何与核心具有增强的规范对称性。时空几何可以与大N塞伯格-威滕理论联系起来。
We study brane configurations that give rise to large-N gauge theories with eight supersymmetries and no hypermultiplets. These configurations include a variety of wrapped, fractional, and stretched branes or strings. The corresponding spacetime geometries which we study have a distinct kind of singularity known as a repulson. We find that this singularity is removed by a distinctive mechanism, leaving a smooth geometry with a core having an enhanced gauge symmetry. The spacetime geometry can be related to large-N Seiberg-Witten theory.
