چکیده
Characteristic classes for the index of the Dirac family [unk](A) are computed in terms of differential forms on the orbit space of vector potentials under gauge transformations. They represent obstructions to the existence of a covariant Dirac propagator. The first obstruction is related to a chiral anomaly.

SADDLE POINT VARIATIONAL METHOD FOR DIRAC CONFINEMENT
A saddle point variational (SPV ) method was applied to the Dirac equation as an example of a fully relativistic equation with both negative and positive energy solutions. The effect of the negative energy states was mitigated by maximizing the energy with respect to a relevant parameter while at the same time minimizing it with respect to another parameter in the wave function. The Cornell pot...
متن کاملEigenfunctions at the Threshold Energies of Magnetic Dirac Operators
We propose a simple proof of characterization of the eigenspaces corresponding to the eigenvalues ±m of a supersymmetric Dirac operatorH = Q+mτ , where Q is a supercharge, m a positive constant, and τ the unitary involution. The proof is abstract, but not relevant to the abstract Foldy-Wouthuysen transformation. We then apply the obtained results to magnetic Dirac operators, and derive a series...
متن کاملEigenfunctions of Dirac Operators at the Threshold Energies
We show that the eigenspaces of the Dirac operator H = α · (D − A(x)) + mβ at the threshold energies ±m are coincide with the direct sum of the zero space and the kernel of the Weyl-Dirac operator σ·(D−A(x)). Based on this result, we describe the asymptotic limits of the eigenfunctions of the Dirac operator corresponding to these threshold energies. Also, we discuss the set of vector potentials...
متن کاملAn L 2-index Theorem for Dirac Operators on S 1 × R 3
An expression is found for the L 2-index of a Dirac operator coupled to a connection on a Un vector bundle over S 1 × R 3. Boundary conditions for the connection are given which ensure the coupled Dirac operator is Fred-holm. Callias' index theorem is used to calculate the index when the connection is independent of the coordinate on S 1. An excision theorem due to Gromov, Lawson, and Anghel re...

In this paper, we improve some recent coupled fixed point resultsfor single-valued operators in the framework of ordered $b$-metricspaces established by Bota et al. [M-F. Bota, A. Petrusel, G.Petrusel and B. Samet, Coupled fixed point theorems forsingle-valued operators in b-metric spaces, Fixed Point TheoryAppl. (2015) 2015:231]. Also, we prove that Perov-type fix...
