Bilinear Spinor Representation of Space-Time [PDF]
In this work a method of realizing the bilinear spinor representation of space-time 1s suggested, in which the usual translation transformation can be established. The basic spinors introduced are the quantities having the spinor structure with respect to the Lorentz transformation group and the isotopic transformation group as well. In the language of

Principal series representations and harmonic spinors
Let \(G\) be a real reductive Lie group and \(G/H\) a reductive homogeneous space. The authors consider Kostants cubic Dirac operator \(D\) on \(G/H\) twisted with a finite-dimensional representation of \(H\). Under the assumption that \(G\) and \(H\) have the same complex rank, the authors construct a nonzero intertwining operator from principal ...

Master formulas for the dressed scalar propagator in a constant field
The worldline formalism has previously been used for deriving compact master formulas for the one-loop N-photon amplitudes in both scalar and spinor QED, and in the vacuum as well as in a constant external field.

On Spinor Varieties and Their Secants
We study the secant variety of the spinor variety, focusing on its equations of degree three and four. We show that in type Dn, cubic equations exist if and only if n ≥ 9. In general the ideal has generators in degrees at least three and four. Finally we

The Spinor Representation of Minimal Surfaces
The spinor representation is developed and used to investigate minimal surfaces in ${\bfR}^3$ with embedded planar ends. The moduli spaces of planar-ended minimal spheres and real projective planes are determined, and new families of minimal tori and Klein bottles are given.

In this article, the propagation of soliton-like vortex beams in the optical segment of a Radio-over-Fiber system is discussed. The approach is based on the solution of the nonlinear Schrdinger equation for the Kerr nonlinear medium like optical fiber. A

In this paper, we give the general expressions for a special series of tree amplitudes of the Yang–Mills theory. This series of amplitudes have two adjacent massless spin-1 particles with extra-dimensional momenta and any number of positive helicity ...

SPINOR REPRESENTATIONS OF PAFORS IN E3
In this paper, we introduce the spinor representations of PAFORS for the trajectories endowed with PAFORS on regular surfaces of Euclidean -space . We find the spinor equations of PAFORS vectors. Moreover, we obtain the relations between spinor representations of PAFORS and Darboux frame.
