AKSZ型拓扑量子场论与有理同伦理论
AKSZ-type Topological Quantum Field Theories and Rational Homotopy Theory
摘要:
我们重新制定和激励AKSZ型拓扑场论在行人的条款,解释他们如何出现作为最一般的施瓦茨型拓扑行动受到一个简单的约束,以及他们如何推广陈$-$西蒙斯理论和其他著名的拓扑场论,因为他们是规范理论的平坦连接的高规范群(无限李代数)。他们的欧拉$-$拉格朗日方程定义准自由分次交换微分代数,或等价的$L_\infty$ -代数,规范群的李代数的等价物;我们解释如何整合出辅助场在物理学对应于采取沙利文极小模型这个代数,以及如何场和规范变换之间的对应关系实现Koszul对偶。使用这个字典,我们可以导入拓扑不变量和概念(例如$~$有理LS-范畴)来应用于这类理论。
英文摘要:
We reformulate and motivate AKSZ-type topological field theories in pedestrian terms, explaining how they arise as the most general Schwartz-type topological actions subject to a simple constraint, and how they generalize Chern$-$Simons theory and other well known topological field theories, in that they are gauge theories of flat connections of higher gauge groups (infinity-Lie algebras). Their Euler$-$Lagrange equations define quasifree graded-commutative differential algebras, or equivalently $L_\infty$-algebras, the equivalent of the Lie algebra of the gauge group; we explain how integrating out auxiliary fields in physics corresponds to taking the Sullivan minimal model of this algebra, and how the correspondence between fields and gauge transformations realizes Koszul duality. Using this dictionary, we can import topological invariants and notions (e.g.$~$the rational LS-category) to apply to this class of theories.
