我们研究了3d $$\mathcal{N}=2$$ N = 2规范理论在边界存在下的全纯扭曲,以及体和边界局域算子的代数结构.在全纯扭曲中,体局部算子和边界局部算子都形成手征代数(又称手征代数)。顶点代数)。体代数是可交换的,具有移位泊松括号和“更高”的应力张量;而边界代数是体的模,可能不是可交换的,可能有也可能没有应力张量。我们明确地构造散装和边界代数的自由理论和朗道-金兹伯格模型。我们构造边界代数规范理论与物质和/或陈-西蒙斯耦合,留下一个完整的描述散装代数未来的工作。我们简要地讨论了存在更高的A-无穷大的结构。
We study the holomorphic twist of 3d $$\mathcal{N}=2$$ N = 2 gauge theories in the presence of boundaries, and the algebraic structure of bulk and boundary local operators. In the holomorphic twist, both bulk and boundary local operators form chiral algebras ( a.k.a. vertex algebras). The bulk algebra is commutative, endowed with a shifted Poisson bracket and a “higher” stress tensor; while the boundary algebra is a module for the bulk, may not be commutative, and may or may not have a stress tensor. We explicitly construct bulk and boundary algebras for free theories and Landau–Ginzburg models. We construct boundary algebras for gauge theories with matter and/or Chern–Simons couplings, leaving a full description of bulk algebras to future work. We briefly discuss the presence of higher A-infinity like structures.
