论文摘要
在这项工作中，已经提出了三级减速参数的新定律。修改场方程的解决方案是根据减速参数的新提出的定律得出的。型号在宇宙时间（$ t = 0 $）展示了大爆炸的奇异性，并在（$ t = n $）上显示大裂口，然后重新进入初始奇点的阶段，$ t = 2n $，并以$ t = 3n $结束其周期性行为。已经研究了宇宙的物理和动力学参数的演变，并显示了图形表示。进一步的$ OM（Z）$诊断参数和能量条件也与其图形表示一起进行了研究。
In this work a new law of varying deceleration parameter of third degree have been proposed. The solutions of the modified field equations have been derived under the newly proposed law of the deceleration parameter. Model exhibits the Big-bang singularity at cosmic time ($t=0$) and shows Big Rip at ($t=n$) then it re-enter the phase of initial singularity at $t=2n$ and ends its cyclic behavior at $t=3n$. The evolution of the physical and dynamical parameters of the Universe have been studied and the graphical representation has also been shown. Further $Om(z)$ diagnostic parameter and the energy conditions have also been studied together with their graphical representations.
