The work reported in this paper explores holographic bounce. In the first phase of the study, we chose a non-singular bouncing scale factor. Then we reconstructed f(T) gravity and analytically derived constraints on the bouncing parameter σ. These constraints helped us understand the scale factor’s quintessence or phantom behavior. Furthermore, we also explored the statefinder parameters for reconstructed f(T) and observed the attainment of ΛCDM fixed point. Next, we considered the multiplicative bouncing scale factor inspired by S. D. Odintsov and V. K. Oikonomou Phys. Rev. D 94, (2016) 064022. For this choice, we discussed the types of singularities realizable for different cases. Through the Talyor series expansion, we analytically presented cases and subcases for different ranges of α of the scale factor. In the last phase of the study, we demonstrated holographic bounce with the choice of the multiplicative scale factor. In this case, we considered holographic Ricci dark energy and Barrow holographic dark energy. We concluded that it is possible to generate constraints on the bouncing parameter for its feasibility for the EoS parameter. We concluded that the realization of holographic bounce is possible, and different suitable constraints can be derived for this multiplicative bouncing scale factor focusing on the realization of cosmic bounce.

用全息背景约束弹跳实现并对修改后的重力框架中的后果进行分析探索

本文报道的工作探讨了全息反射。在研究的第一阶段,我们选择了非奇异的弹跳比例因子。然后我们重构了F时间重力和分析得出的弹跳参数约束σ。这些约束帮助我们理解比例因子的精髓或幻象行为。此外,我们还探索了重建的状态探测器参数F时间并观察了达到ΛCDM 定点。接下来,我们考虑了受 SD Odintsov 和 VK Oikonomou Phys 启发的乘法弹跳比例因子。Rev. D  94 , (2016) 064022。对于这种选择,我们讨论了不同情况下可实现的奇点类型。通过 Talyor 系列扩展,我们分析性地呈现了不同范围的案例和子案例α的比例因子。在研究的最后阶段,我们通过选择乘法比例因子来演示全息反射。在这种情况下,我们考虑了全息里奇暗能量和巴罗全息暗能量。我们得出的结论是,可以对弹跳参数生成约束,以保证其对于 EoS 参数的可行性。我们得出的结论是,全息反射的实现是可能的,并且可以针对该乘法反射比例因子导出不同的合适约束,重点关注宇宙反射的实现。
