چکیده

We study the problem of quantization of thin shells in a Weyl–Dirac theory by deriving a Wheeler–DeWitt equation from the dynamics. Solutions are found which have interpretations in both cosmology and particle physics.

Branes from Moyal Deformation Quantization of Generalized Yang Mills Theories

It is shown that a Moyal deformation quantization of the SO(4k) Generalized Yang-Mills (GYM) theory action in D = 4k dimensions, for spacetime independent field configurations, in the h̄ → 0 limit, yields the Dolan-Tchrakian p-brane action after fixing the conformal and world volume reparametrization invariance , associated with the p-brane world volume dimension p + 1 = 4k, embedded in a D = 4k...

Noncommutative Quantum Gravity

The possible role of gravity in a noncommutative geometry is investigated. Due to the Moyal *-product of fields in noncommutative geometry, it is necessary to complexify the metric tensor of gravity. We first consider the possibility of a complex Hermitian, nonsymmetric gμν and discuss the problems associated with such a theory. We then introduce a complex symmetric (non-Hermitian) metric, with...

We give an example of a spacetime having an infinite thin rotating cylindrical shell constituted by a charged perfect fluid as a source. As the interior of the shell the Bonnor–Melvin universe is considered, while its exterior is represented by Datta– Raychaudhuri spacetime. We discuss the energy conditions and we show that our spacetime contains closed timelike curves. Trajectories of charged ...

Twisted Covariance vs Weyl Quantisation

In this letter we wish to clarify in which sense the tensor nature of the commutation relations [x,x ] = iθ underlying Minkowski spacetime quantisation cannot be suppressed even in the twisted approach to Lorentz covariance. We then address the vexata quaestio: “why θ?”
