论文摘要
我们研究2D $ \ MATHCAL {N} =（2,2）$ QUIVER GAUGE理论没有风味节点。有一类特殊的QUIVERS仪表组在任何双重性框架中保持积极的态度。我们用Abelian Kronecker Quiver和Abelian Markov颤抖作为最简单的例子来说明这一点。在几何阶段，他们分别在卡拉比远的空间中设计了一个无限的射击空间和超曲面序列。我们表明，马尔可夫Quiver提供了SU（3）SQCD的Abelianization。打开FI参数和Abelian颤动的$θ$角有效地通过此类参数变形了SQCD。对于与SU（$ K $）SQCD相对应的Abelian项链箭袋，我们找到了KählerModuli Space中非紧凑型库仑分支的奇异基因座的证据。
We study 2d $\mathcal{N}=(2,2)$ quiver gauge theories without flavor nodes. There is a special class of quivers whose gauge group ranks stay positive in any duality frame. We illustrate this with the Abelian Kronecker quiver and the Abelian Markov quiver as the simplest examples. In the geometric phase, they engineer an infinite sequence of projective spaces and hypersurfaces in Calabi-Yau spaces, respectively. We show that the Markov quiver provides an Abelianization of SU(3) SQCD. Turning on the FI parameters and the $θ$ angles for the Abelian quiver effectively deform SQCD by such parameters. For an Abelian necklace quiver corresponding to SU($k$) SQCD, we find evidence for singular loci supporting non-compact Coulomb branches in the Kähler moduli space.
