摘要:

利用D-膜工程,在五维SU(r)规范理论中,构造了束缚于表面算符的BPS态的超对称量子力学模型。该模型代表了某种D2-膜结构的有效作用,并且是通过对$(0,2)$规范线性西格玛模型进行降维而自然得到的。在一个特殊的稳定腔中,所得到的模空间的投影表示是几乎光滑的,同构于一个模空间的框架投影平面上的投影。对于锥状和局部P^1 x P^1几何,给出了一个精确的猜想,它把这个模空间的K-理论配分函数与复曲面拉格朗日膜的开弦不变量联系起来.

英文摘要:

A supersymmetric quantum mechanical model is constructed for BPS states bound to surface operators in five dimensional SU(r) gauge theories using D-brane engineering. This model represents the effective action of a certain D2-brane configuration, and is naturally obtained by dimensional reduction of a quiver $(0,2)$ gauged linear sigma model. In a special stability chamber, the resulting moduli space of quiver representations is shown to be virtually smooth and isomorphic to a moduli space of framed quotients on the projective plane. A precise conjecture relating a K-theoretic partition function of this moduli space to refined open string invariants of toric lagrangian branes is formulated for conifold and local P^1 x P^1 geometries.
