平丛和具有(1,1)联络的全纯丛的复值解析挠率

Complex Valued Analytic Torsion for Flat Bundles and for Holomorphic Bundles with (1,1) Connections

Sylvain E. Cappell, Edward Y. Miller

摘要:

雷和辛格的工作,其中介绍了解析挠,一种决定性的拉普拉斯算子在拓扑和全纯设置,自然是推广在这两个设置。在拓扑环境中,耦合被直接推广到一般的平坦丛,在全纯环境中,耦合被推广到具有(1,1)联络的丛,利用Newlander-Nirenberg定理,耦合被看作是具有全纯和反全纯结构的丛.由此产生的拉普拉斯算子的自然推广并不总是自伴的,因此相应的解析挠的推广并不总是实值的。Cheeger-Muller定理,等价于在拓扑设置的解析扭转经典的拓扑扭转,推广到这个复值扭转。在代数方面的方法介绍包括一个概念的扭转相关的复杂配备了边界和coboundry地图。

英文摘要:

The work of Ray and Singer which introduced analytic torsion, a kind of determinant of the Laplacian operator in topological and holomorphic settings, is naturally generalized in both settings. The couplings are extended in a direct way in the topological setting to general flat bundles and in the holomorphic setting to bundles with (1,1) connections, which using the Newlander-Nirenberg Theorem are seen to be the bundles with both holomorphic and anti-holomorphic structures. The resulting natural generalizations of Laplacians are not always self-adjoint and the corresponding generalizations of analytic torsions are thus not always real-valued. The Cheeger-Muller theorem, on equivalence in a topological setting of analytic torsion to classical topological torsion, generalizes to this complex-valued torsion. On the algebraic side the methods introduced include a notion of torsion associated to a complex equipped with both boundary and coboundry maps.
