标题： Symmetries and Observables for BF-theories in Superspace

摘要： 研究了描述平坦联络的拓扑量子场论的超对称版本——超BF理论，并采用超空间形式化方法。从超空间的曲率中推导出一组与拓扑不变量相关的可观测量。类似于非超对称版本，该理论表现出矢量型超对称性。文中解释了矢量超对称性和作用量的额外新对称性在构造可观测量中的作用。 显示英文摘要

摘要： The supersymmetric version of a topological quantum field theory describing flat connections, the super BF-theory, is studied in the superspace formalism. A set of observables related to topological invariants is derived from the curvature of the superspace. Analogously to the non-supersymmetric versions, the theory exhibits a vector-like supersymmetry. The role of the vector supersymmetry and an additional new symmetry of the action in the construction of observables is explained.
