Geometric connections and geometric Dirac operators on contact manifolds
نویسنده
چکیده
We construct some natural metric connections on metric contact manifolds compatible with the contact structure and characterized by the Dirac operators they determine. In the case of CR manifolds these are invariants of a fixed pseudo-hermitian structure, and one of them coincides with the Tanaka–Webster connection. 2005 Elsevier B.V. All rights reserved.

On index formulas for manifolds with metric horns
In this paper we discuss the index problem for geometric differential operators (Spin-Dirac operator, Gauß-Bonnet operator, Signature operator) on manifolds with metric horns. On singular manifolds these operators in general do not have unique closed extensions. But there always exist two extremal extensions Dmin and Dmax. We describe the quotient D(Dmax)/D(Dmin) explicitely in geometric resp. ...
متن کاملSome remarks on the geometric quantization of contact manifolds
Suppose that (M,E) is a compact contact manifold, and that a compact Lie group G acts on M transverse to the contact distribution E. In [14], we defined a G-transversally elliptic Dirac operator Db / , constructed using a Hermitian metric h and connection ∇ on the symplectic vector bundle E → M , whose equivariant index is well-defined as a generalized function on G, and gave a formula for its ...
متن کاملClifford Algebroids and Nonholonomic Einstein–Dirac Structures
We propose a new framework for constructing geometric and physical models on spacetimes provided with Lie algebroid symmetry, i.e. manifolds provided with additional anchor and generalized Lie algebra commutator structures. The approach is related to the geometry of moving nonholonomic frames with associated nonlinear connections. A strict application of such geometric methods to spinor fields ...
متن کاملGeneralized Dirac Operators on Nonsmooth Manifolds and Maxwell’s Equations
We develop a function theory associated with Dirac type operators on Lipschitz subdomains of Riemannian manifolds. The main emphasis is on Hardy spaces and boundary value problems, and our aim is to identify the geometric and analytic assumptions guaranteeing the validity of basic results from complex function theory in this general setting. For example, we study PlemeljCalderón-Seeley-Bojarski...
متن کاملThe Srni Lectures on Non-integrable Geometries with Torsion
This review article intends to introduce the reader to non-integrable geometric structures on Riemannian manifolds and invariant metric connections with torsion, and to discuss recent aspects of mathematical physics—in particular superstring theory—where these naturally appear. Connections with skew-symmetric torsion are exhibited as one of the main tools to understand non-integrable geometries...
