The Chern Character of {\theta}-summable Fredholm Modules over dg Algebras and the Supersymmetric Path Integral

  title={The Chern Character of \{\theta\}-summable Fredholm Modules over dg Algebras and the Supersymmetric Path Integral},
  author={Batu Guneysu and Matthias Ludewig},
  journal={arXiv: K-Theory and Homology},
We introduce the notion of a {\theta}-summable Fredholm module over a locally convex dg algebra {\Omega} and construct its Chern character as an entire cyclic cocyle in the entire cyclic complex of {\Omega}, leading to a cohomology class in the entire cyclic cohomology of {\Omega}. This extends the cocycle of Jaffe, Lesniewski and Osterwalder to the differential graded case. Using this Chern character, we prove an index theorem involving an abstract version of a Bismut-Chern character… 

A Rigorous Construction of the Supersymmetric Path Integral Associated to a Compact Spin Manifold

We give a rigorous construction of the path integral in $${\mathcal {N}}=1/2$$ N = 1 / 2 supersymmetry as an integral map for differential forms on the loop space of a compact spin

Mini-Workshop: Recent Progress in Path Integration on Graphs and Manifolds

The diverse backgrounds – analysis, geometry, mathematical physics and probability theory – created a productive atmosphere leading to discussions on new developments, advance projects and establishing new collaborations.

Construction of the Supersymmetric Path Integral: A Survey

This is a survey based on joint work with Florian Hanisch and Batu G\"uneysu reporting on a rigorous construction of the supersymmetric path integral associated to compact spin manifolds.



A Bivariant Chern Character¶for Families of Spectral Triples

Abstract: In this paper we construct a bivariant Chern character defined on “families of spectral triples”. Such families should be viewed as a version of unbounded Kasparov bimodules adapted to the

Quantum $K$-theory. I. The Chern character

We construct a cocycle on an infinite dimensional generalization of ap-summable Fredholm module. Our framework is related to Connes' cyclic cohomology and is motivated by our work on index theory on

A∞ algebras and the cyclic bar complex.

This paper arose from our use of Chen’s theory of iterated integrals as a tool in the study of the complex of SX-equivariant differential forms on the free loop space LX of a manifold X (see [2]). In

The fixed point theorem in equivariant cohomology

In this paper we study the S -equivariant de Rham cohomology of infinite dimensional S -manifolds. Our main example is the free loop space LX where X is a finite dimensional manifold with the circle

Path integrals, supersymmetric quantum mechanics, and the Atiyah-Singer index theorem for twisted Dirac

Feynman’s time-slicing construction approximates the path integral by a product, determined by a partition of a finite time interval, of approximate propagators. This paper formulates general

Odd characteristic classes in entire cyclic homology and equivariant loop space homology

Given a compact manifold $M$ and $g\in C^{\infty}(M,U(l;\mathbb{C}))$ we construct a Chern character $\mathrm{Ch}^-(g)$ which lives in the odd part of the equivariant (entire) cyclic Chen-normalized

Index theorem and equivariant cohomology on the loop space

In this paper, extending ideas of Witten and Atiyah, we describe some relations of equivariant cohomology on the loop space of a manifold to the path integral representation of the index of the Dirac
