Abstract
The present work is devoted to investigation of non-static plane symmetric universe filled with matter and anisotropic modified holographic Ricci dark energy components within the framework of a scalar-tensor theory formulated by Saez and Ballester (1986).â¯To get the determinate solution of the model we have used scalar expansion proportional to the shear scalar, linearly varying deceleration parameter and energy density of modified holographic Ricci dark energy.â¯We study the equation of state parameter (ÏÎ), deceleration parameter (q), squared speed of sound (vs2) and ÏÎ-ÏÎâ² and r-s planes for our dark energy model.â¯The equation of state parameter provides a quintom-like behavior of the universe.â¯The r-s plane corresponds to ÎCDM limit, Chaplygin and phantom regions, whereasâ¯ÏÎ-ÏÎâ² trajectories correspond to both thawing and freezing regions.
