Inhomogeneous cosmology with spinning fluid

Неоднородная космология с вращающейся средой

  • Published:
Il Nuovo Cimento B (1971-1996)

Summary

The energy-momentum tensor of a spinning fluid written in a form structurally similar to that of an imperfect fluid is used to investigate the evolution of an inhomogeneous and anisotropic cosmological model. It is observed that the model evolves into the Friedmann model due to the effect of spin.

Riassunto

Si usa il tensore energia-momento di un fluido in moto vorticoso in una forma strutturalmente simile a quella di un fluido imperfetto per studiare l’evoluzione di un modello cosmologico inomogeneo e anisotropico. Si osserva che il modello evolve nel modello di Friedmann a causa dell’effetto di spin.

Резюме

Тензор энергии-импульса для вращающейся среды, записанный в структурно аналогичной форме тензора энергии-импульса для идеальной жидкости, используется для исследования эволюции неоднородной и анизотропной космологической модели. Обнаружено, что предложенная модель развивается в модель фридмана, вследствие учета эффекта спина.
