Abstract
In this article, we analyze Marder-type space-time in the framework of general relativity theory, with viscous holographic dark energy. To solve the field equations, we use the shear scalar is proportional to the expansion scalar which leads to a relation between metric potentials and hybrid expansion law (HEL) proposed by Akarsu et al. (J Cosmol Astropart Phys 01:022, 2014). Also, we determine the cosmological parameters, namely the deceleration parameter(q), jerk parameter (j), statefinder parameters , equation of state parameter () and plane for the obtained model. The derived model supports the accelerating behavior of the Universe along with the null, weak and dominant energy conditions that are obeyed by violating strong energy condition as per the present accelerated expansion.
