摘要：

在$\mathcal N \geq 2$超共形Chern-Simons-matter理论中，我们构造了Bogomol'nyi-Prasad-Sommerfield（BPS）威尔逊圈的无限族，它与标量和费米子物质具有常数参量耦合，包括Minkowski时空中的线威尔逊圈和欧氏空间中的圆威尔逊圈.我们发现最一般的BPS威尔逊圈的联络不能用双结点联络来分解。此外，如果矩阵包含三角形，它不能被解释为超代数中的超矩阵。然而，对于参数的特定选择，它简化为Aharony-Bergman-Jafferis-Maldacena（ABJM）理论中的1/6 BPS威尔逊圈和$\mathcal N = 4$轨道折叠ABJM理论中的1/4 BPS威尔逊圈的众所周知的连接。在$\mathcal N = 2$ orbifold ABJM理论的特殊情况下，我们确定了一个子集的运营商的重力场。通过研究费米和玻色子BPS威尔逊圈的期望值，在量子水平上研究了它们的上同调等价性，并找到了强有力的证据证明了在框架1下，上同调等价性在量子力学上成立.最后，我们讨论了一个更强的配方的上同调等价，这意味着非平凡的身份关联函数的复合运营商在缺陷CFT定义的威尔逊轮廓，并允许作出新的预测，相应的未知积分，要求确认。

英文摘要：

In $\mathcal N \geq 2$ superconformal Chern-Simons-matter theories we construct the infinite family of Bogomol'nyi-Prasad-Sommerfield (BPS) Wilson loops featured by constant parametric couplings to scalar and fermion matter, including both line Wilson loops in Minkowski spacetime and circle Wilson loops in Euclidean space. We find that the connection of the most general BPS Wilson loop cannot be decomposed in terms of double-node connections. Moreover, if the quiver contains triangles, it cannot be interpreted as a supermatrix inside a superalgebra. However, for particular choices of the parameters it reduces to the well-known connections of 1/6 BPS Wilson loops in Aharony-Bergman-Jafferis-Maldacena (ABJM) theory and 1/4 BPS Wilson loops in $\mathcal N = 4$ orbifold ABJM theory. In the particular case of $\mathcal N = 2$ orbifold ABJM theory we identify the gravity duals of a subset of operators. We investigate the cohomological equivalence of fermionic and bosonic BPS Wilson loops at quantum level by studying their expectation values, and find strong evidence that the cohomological equivalence holds quantum mechanically, at framing one. Finally, we discuss a stronger formulation of the cohomological equivalence, which implies non-trivial identities for correlation functions of composite operators in the defect CFT defined on the Wilson contour and allows to make novel predictions on the corresponding unknown integrals that call for a confirmation.
