Axially Symmetric Bianchi Type-I Model with Massless Scalar Field and Cosmic Strings in Barber’s Self-Creation Cosmology

“…On integration, (2.20) yields two basic solutions for φ as The energy density ρ associated with the massless scalar field ν (Mohanty [17,18]; Panigrahi and Sahu [19]) is given by (2.13)] that rest energy density (for strings) ε = 0. Hence particle density (for strings) ε p = 0.…”

Axially Symmetric Cosmological Micro Model in Barber’s Modified Theory of Einstein General Relativity

“…Singh and Deo [3], Reddy [4][5][6], Maharaj and Beesham [7], Venkateswarlu and Reddy [8][9][10], Shanti and Rao [11], Mohanty et al [12,13] are some of the authors who have investigated various aspects of Barber's self creation theories. Mohanty et al [14] have obtained a micro and macro cosmological models in the presence of massless scalar field interacted with perfect fluid. Panigrahi and Sahu [15][16][17] have also obtained plane symmetric inhomogeneous cosmological micro and macro models and plane symmetric mesonic stiff fluid models in Barber's second theory of gravitation.…”

Wet Dark Fluid Cosmological Model in Barber Self-Creation Theory of Gravitation

“…Many authors [3][4][5][6][7][8][9][10][11][12] have investigated various aspects of Barber second self-creation theory by using various cosmological models.…”
