Bianchi Type-II String Cosmological Model with Magnetic Field in Scalar-tensor Theory of Gravitation

Bianchi Type-I Cosmological Model with Null Radiation Flow

“…The simplest Bianchi family is the Bianchi type-I space time that contains the flat FRW universe as a special case. Several authors studied the cosmological models with constant and time dependent displacement field [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. The matter content universe is not expected to attain thermal equilibrium at the time of its evolution, it is evident that there would be heat flow in the universe.…”
