Viscous Ricci Dark Energy Cosmological Models In Brans-Dicke Theory

View through CrossRef
The whole article deals with the analysis of the cosmic model of Ruban's space-time in the context of a bulk viscosity impact in the form of Ricci dark energy within the framework Brans- Dicke theory. We believe that outer space is filled with dark matter and viscous Ricci dark energy (VRDE) under the pressureless situation. The velocity and rate at which the Universe is expanding are presumed to be proportional to the coefficient of total bulk viscosity, is in the form, a / a a / a 0 1 2 , where 0 , 1 and 2 are the constants. To solve the RDE model's field equations, we utilize the relation among the metric potentials and also the power-law relation among the average scale factor a(t) and scalar field . Статья посвящена анализу космической модели пространства времени Рубана в контексте воздействия объемной вязкости в форме темной энергии Риччи в рамках теории Бранса-Дикке. Мы считаем, что внешний космос заполнен темной материей и вязкой темной энергией Риччи (VRDE) в условиях отсутствия давления. Предполагается, что скорость и расширения Вселенной пропорциональны коэффициенту общей объемной вязкости.
