We investigated the possibility of construction homogeneous and isotropic cosmological solutions in Weyl geometry. derived self-consistency condition which ensures conformal invariance complete set equations motion. There is special gauge choosing factor when vector equals zero. In this we found new vacuum absent General Relativity. Also, solution geometry for radiation dominated universe with ...

I characterize the structure of the master field for F 0 z ¯ z in SU(∞)-Y M 4 on a product of two Riemann surfaces Z × W in the gauge F ch z ¯ z = 0 as the sum of a 'bulk' constant term and of delta-like 'contact' terms. The contact terms may occur because the localization of the functional integral at N = ∞ on a master orbit of a constant connection under the action of singular gauge transform...

CTS began manufacturing pointing devices in 1994 for use as cursor controls, mounted in the keyboards of notebook computers. While completed keyboards were robust against ESD, many precautions were required during manufacture and assembly to protect against the effects of ESD. While these ESD “protective” controls were effective in controlling ESD, they did not eliminate the ESD susceptibility ...

Electromagnetic properties of off-shell particles are discussed on the sis of a purely electromagnetic reaction: virtual Compton scattering off a proton. It is shown that the definition of off-shell electromagnetic form factors is not gauge invariant and they cannot be investigated in practice. Using only fundamental requirements of gauge invariance it is demonstrated that off-shell effects are...

A large-scale, relativistic configuration-interaction ~RCI! method has been developed for precision calculations of transition oscillator strengths. It is based on the no-pair Hamiltonian and employs finite B-spline basis functions. For the 2s S0 –2s2p P1 intercombination transition in berylliumlike carbon, the present RCI expansions reach close to 200 000 configurations, and include all single...

We study the finite temperature properties of the gauge theory of nonrelativistic fermions introduced by Halperin, Lee, and Read. This gauge theory is relevant to two interesting systems: high-Tc superconductors in the anomalous metallic phase and a two-dimensional electron system in a strong magnetic field at the Landau filling factor ν = 1/2. We calculate the self-energies of both gauge boson...

In the slitting method, a small width slit is created incrementally through the thickness of the stressed specimen and the released strains in each increment are recorded by a strain gauge. Compliance coefficients relate the measured strains to the residual stresses. This paper investigates the important parameters influencing the calculation of compliance coefficients for isotropic plates and ...
