The Dirac oscillator in a spinning cosmic string spacetime
Mansoureh Hosseinpour, Hassan Hassanabadi, Marc de Montigny
We examine the effects of gravitational fields produced by topological defects on a Dirac field and a Dirac oscillator in a spinning cosmic string spacetime. We obtain the eigenfun…
Path-integral quantization of Galilean Fermi fields
M. de Montigny, F. C. Khanna, F. M. Saradzhev
The Galilei-covariant fermionic field theories are quantized by using the path-integral method and five-dimensional Lorentz-like covariant expressions of non-relativistic field equ…
Elements of Finite Order in Lie Groups and Discrete Gauge Symmetries
Marc de Montigny
We apply Kac's theory of elements of finite order (EFO) in Lie groups to the description of discrete gauge symmetries in various supersymmetric grand unified models. Taking into ac…
Graded contractions of bilinear invariant forms of Lie algebras
Marc de Montigny
We introduce a new construction of bilinear invariant forms on Lie algebras, based on the method of graded contractions. The general method is described and the -, $\Bbb…
Cayley-Klein Algebras as Graded Contractions of so(N+1)
F. J. Herranz, M. de Montigny, M. A. del Olmo +1
We study graded contractions of the real compact simple Lie algebra , and we identify within them the Cayley-Klein algebras as a naturally distingui…
