Abstract

We report on the results of our work [1], which discusses \(\mathcal{N} = 2\) nonlinear sigma models on the quadrics of the Grassmann manifold and three-pronged junctions of the mass-deformed nonlinear sigma models on \(SO(8){\text{/}}U(4)\) and \(Sp(3){\text{/}}U(3)\). This article is prepared for the Proceedings of International Workshop “Supersymmetries and Quantum Symmetries—SQS’2019”, which was held in Yerevan from 26 to 31 August, 2019. The talk was based on [1].

SO（2 N）/ U（N）和Sp（N）/ U（N）的三管结

摘要

我们报告我们的工作结果[1]，该结果讨论了Grassmann流形二次曲面上的\（\ mathcal {N} = 2 \）非线性sigma模型和\上质量变形的非线性sigma模型的三叉结。（SO（8）{\ text {/}} U（4）\）和\（Sp（3）{\ text {/}} U（3）\）。本文是为2019年8月26日至31日在埃里温举行的“超对称和量子对称-SQS'2019”国际研讨会论文集准备的。演讲基于[1]。
