膜镶嵌与非交换几何

Brane Tilings and Non-Commutative Geometry

Richard Eager

摘要:

通过计算Van den Bergh首先构造的倾斜物体的自同态代数,我们导出了关于横切于L(a,b,c)奇点的D3-膜的世界体积的规范规范理论。通过将一个图嵌入面心立方晶格中,可以简明地描述量子规范理论。在这个描述中,规范理论的平面Seiberg对偶通过改变图嵌入而起作用。我们使用这种描述的Seiberg对偶性,以显示这些规范规范理论具有周期Seiberg对偶的存在,预计从AdS/CFT对应。

英文摘要:

We derive the quiver gauge theory on the world-volume of D3-branes transverse to an L(a,b,c) singularity by computing the endomorphism algebra of a tilting object first constructed by Van den Bergh. The quiver gauge theory can be concisely specified by an embedding of a graph into a face-centered cubic lattice. In this description, planar Seiberg dualities of the gauge theory act by changing the graph embedding. We use this description of Seiberg duality to show these quiver gauge theories possess periodic Seiberg dualities whose existence was expected from the AdS/CFT correspondence.
