AbstractAbstract
[en] With the Coulomb gauge, the Chern-Simons-Georgi-Glashow (CSGG) model is quantized in the Dirac formalism for the constrained system. Combining the Gauss law and Coulomb gauge consistency condition, the difference between the Schwinger angular momentum and canonical angular momentum of the system is found to be an anomalous spin. The reason for this result lies in the fact that the Schwinger energy momentum tensor and the canonical one have different symmetry properties in the presence of the Chern-Simons term. (authors)

AbstractAbstract
[en] Starting with the algebraic classification of the energy-momentum tensor given by Plebansky, it is established that this classification is unstable under versal deformations and a new (stable) classification is given. In order to keep the text to reasonable length, we just write the basic ideas and some results. (Author) (Author)

AbstractAbstract
[en] The physical structure of the energy-momentum tensor is of great importance in General Relativity. In the last few years many people have discussed various aspects of this subject. The present study discusses some of the algebraic and geometric interpretations of these physical structures. It will be shown how a systematic use of the theory of the classification of energy-momentum tensors greatly simplifies many problems. (author)

AbstractAbstract
[en] It was pointed out some time ago that in a supersymmetric theory the axial current j5μ, the improved energy-momentum tensor θμν and the improved supersymmetry current Sμ can be identified with the components of a superfield. Vμ, so that an intimate relation exists between them. This paper discusses how, at the classical level, this superfield satisfies certain relations reflecting the conservation and trace relations (modulo mass terms)

AbstractAbstract
[en] We have investigated some cosmic transit models in the framework of an extended gravity theory where the usual Ricci scalar in the gravitational action is replaced by a sum of the Ricci scalar and a term proportional to the trace of the energy momentum tensor. A hybrid scale factor is assumed to simulate the cosmic transit behaviour. The hybrid scale factor has two parameters that describe the behaviour of the model at an initial epoch and at a late epoch. The parameters of the hybrid scale factor have been constrained from the cosmic transit behaviour. Four different cosmic transit models have been constructed and are confronted with the observational Hubble parameter data. A cosmographic test for the cosmic transit models is conducted to assess their dynamical evolution. The effect of the model parameters on the cosmic dynamics has been investigated. (paper)

AbstractAbstract
[en] Padmanabhan’s emergent cosmic space proposal is exploited to study the Rastall theory which involves modifying the covariant conservation law of energy-momentum tensor. As necessary elements for this approach, we firstly find the Komar energy and the general entropy of apparent horizon in this theory. After that, a modified expansion law is invoked to re-obtain the Friedmann equations. (note)

AbstractAbstract
[en] The energy-momentum tensor of areal objects in the Riemannian world is considered. These objects are called aether fibres and appear as elements—constituents of a specific matter called the aether one.
