Motivated by the work of Nojiri et al., Phys. Lett. B 797, 134829 (2019), the present study demonstrates inflation driven by holographic DBI-essence scalar field. Considering a simple correction due to the Ultraviolet cutoff, we have studied the slow-roll parameters. It has been observed that the role of the UV-cutoff is not negligible and in the limiting case of [Formula: see text] the inflationary model is characterized by Type-III singularity but can avoid Big-Rip singularity. Finally, it has been observed that the trajectories in [Formula: see text] are compatible with the observational bound found by Planck. It has been concluded that the tensor to scalar ratio for this model can explain the primordial fluctuation in the early universe as well. However, under the purview of [Formula: see text] inflation, although the DBI-essence scalar field can explain primordial fluctuation, the holographic DBI-essence scalar field does not lead to [Formula: see text] trajectory satisfying the Planck’s observational bound.

调查由 DBI 本质标量场驱动的通货膨胀

受到 Nojiri 等人的工作的启发，Phys。莱特。B 797, 134829 (2019)，本研究证明了由全息 DBI 本质标量场驱动的暴胀。考虑到紫外线截止的简单校正，我们研究了慢滚参数。已经观察到 UV 截止的作用不可忽略，并且在 [公式：见文本] 的极限情况下，暴胀模型的特征是 III 型奇点，但可以避免 Big-Rip 奇点。最后，已经观察到[公式：见正文]中的轨迹与普朗克发现的观测界限是相容的。已经得出结论，该模型的张量标量比也可以解释早期宇宙的原始涨落。然而，在[公式：见正文]通货膨胀的范围内，
