摘要：

We investigate the cosmological scenario involving spatially homogeneous and anisotropic Bianchi type-VI0 space-time in the context of the Sharma-Mittal holographic dark energy model within the framework of Brans-Dicke's theory of gravitation. In order to achieve this objective, the Hubble, deceleration, equation -of -state parameters have been discussed. The deceleration parameter (q) is used to measure the pace at which the expansion of the universe is accelerating. The equation -of -state parameter (omega(smhde)) characterizes the quintessence and vacuum areas of the universe. All the parameters demonstrate consistent behaviour following the Planck 2018 data. We assess the dynamical stability by defining the squared speed of sound and examining its behaviour. In addition, the energy conditions and the variation of omega(smhde) and omega(smhde)' in the model indicate the present accelerating expansion of the universe.
