The zero-gravity Kerr-Newman (zGKN) spacetime has been studied extensively. In reference 9 it was shown that the discrete spectrum of the Dirac Hamiltonian on zGKN is nonempty. In an upcoming paper we classify the discrete spectrum and show that the spectrum is indexed by three integers. See Theorem 2.1 below. It was conjectured that the discrete spectrum of the Dirac Hamiltonian on zGKN should converge to the Bohr-Sommerfeld spectrum of the usual Hydrogen problem on Minkowski spacetime with a…

On the discrete Dirac spectrum of a point electron in the zero-gravity Kerr–Newman spacetime

The discrete spectrum of the Dirac operator for a point electron in the maximal analytically extended Kerr–Newman spacetime is determined in the zero- G limit (z GKN), under some restrictions on the

On a zero-gravity limit of the Kerr--Newman spacetimes and their electromagnetic fields

We discuss the limit of vanishing $G$ (Newton's constant of universal gravitation) of the maximal analytically extended Kerr--Newman electrovacuum spacetimes {represented in Boyer--Lindquist

The Dirac point electron in zero-gravity Kerr–Newman spacetime

Dirac’s wave equation for a point electron in the topologically nontrivial maximal analytically extended electromagnetic Kerr–Newman spacetime is studied in a limit G → 0, where G is Newton’s

On the Eigenvalues of the Chandrasekhar-Page Angular Equation

In this paper we study for a given azimuthal quantum number κ the eigenvalues of the Chandrasekhar–Page angular equation with respect to the parameters μ≔am and ν≔aω, where a is the angular momentum

The quantum theory of the electron

The new quantum mechanics, when applied to the problem of the structure of the atom with point-charge electrons, does not give results in agreement with experiment. The discrepancies consist of

Topology of Some Spheroidal Metrics

The solutions of Einstein's vacuum field equations, Rμν = 0, are found when quasi‐oblate and prolate spheroidal coordinates are used. The solutions for the ``Newtonian'' potential can be written as a

Cartan frames and the general relativistic Dirac equation.

The Dirac equation for spin‐½ particles in curved space‐time is formulated using Cartan calculus. Unlike previous formulations, this method is easy to use because it expresses the Dirac equation in

Eigenvalues of the Chandrasekhar–Page angular functions

The Chandrasekhar–Page angular functions for the Dirac equation in the Kerr–Newman background are expanded as series of hypergeometric polynomials, and a three‐term recurrence relation is derived for

Dirac’s equation for the electron in Kerr geometry is separated; and the general solution is expressed as a superposition of solutions derived from a purely radial and a purely angular equation.

Qualitative Theory of Planar Differential Systems

This book deals with systems of polynomial autonomous ordinary differential equations in two real variables. The emphasis is mainly qualitative, although attention is also given to more algebraic
