摘要从同调代数的角度分析了可微流形的量子Chern-Simons不变量。给定一个流形M和一个李(或者更一般地说,一个L∞)代数g,向量空间H(M)g具有一个L∞代数的结构,其同伦类型是M的同伦不变量。我们制定的必要条件和充分条件,这个L∞代数有一个量子提升。我们还得到了关于幺模L∞代数的结构结果,并引入了一个连接幺模和循环L∞代数的加倍构造.
Abstract Quantum Chern–Simons invariants of differentiable manifolds are analyzed from the point of view of homological algebra. Given a manifold M and a Lie (or, more generally, an L∞) algebra g, the vector space H⁎(M)⊗ g has the structure of an L∞ algebra whose homotopy type is a homotopy invariant of M. We formulate necessary and sufficient conditions for this L∞ algebra to have a quantum lift. We also obtain structural results on unimodular L∞ algebras and introduce a doubling construction which links unimodular and cyclic L∞ algebras.
