Invariant Theory and Differential Operators
Constructive invariant theory was a preoccupation of many nineteenth century mathematicians, but the topic fell out of fashion in the early twentieth century. In the latter twentieth century the topic enjoyed a resurgence, partly due to its connections with the construction of moduli spaces in algebraic geometry and partly due to the development of computational algorithms suitable for implemen...
متن کاملΗ - Invariant and Modular Forms
We show that theAtiyah–Patodi–Singer reducedη-invariant of the twisted Dirac operator on a closed 4m− 1-dimensional spin manifold, with the twisted bundle being the Witten bundle appearing in the theory of elliptic genus, is a meromorphic modular form of weight 2m up to an integral q-series. We prove this result by combining our construction of certain modular characteristic forms associated to...
متن کاملLoop Differential K-theory
In this paper we introduce an equivariant extension of the ChernSimons form, associated to a path of connections on a bundle over a manifold M , to the free loop space LM , and show it determines an equivalence relation on the set of connections on a bundle. We use this to define a ring, loop differential K-theory of M , in much the same way that differential K-theory can be defined using the C...
متن کاملDomain Wall Fermions and the η-Invariant
We extend work by Callan and Harvey and show how the phase of the chiral fermion determinant in four dimensions is reproduced by zero modes bound to a domain wall in five dimensions. The analysis could shed light on the applicability of zero mode fermions and the vacuum overlap formulation of Narayanan and Neuberger for chiral gauge theories on the lattice.
متن کاملη-invariant and flat vector bundles II
We first apply the method and results in the previous paper to give a new proof of a result (hold in C/Z) of Gilkey on the variation of ηinvariants associated to non self-adjoint Dirac type operators. We then give an explicit local expression of certain η-invariant appearing in recent papers of Braverman-Kappeler on what they call refined analytic torsion, and propose an alternate formulation o...
