“…Motivated by the above considerations, recently various modified LQC models have been proposed, see, for example (Alesci and Cianfrani, 2013;Alesci and Cianfrani, 2015;Alesci et al, 2017;Oriti, 2017;Oriti et al, 2017;Wilson-Ewing, 2017;Engle and Vilensky, 2018;Gerhardt et al, 2018;Wilson-Ewing, 2018;Baytas et al, 2019;Engle and Vilensky, 2019;Neuser et al, 2019;Olmedo and Alesci, 2019;Han and Liu, 2020a;Han and Liu, 2020b;Han et al, 2020;Li et al, 2020b), and references therein. In this brief review, we have restricted ourselves only to mLQC-I and mLQC-II (Yang et al, 2009;Dapor and Liegener, 2018a;Dapor and Liegener, 2018b), as they are the ones that have been extensively studied in the literature not only the dynamics of the homogeneous Universe (Li et al, 2018a;Li et al, 2018b;Saini and Singh, 2019a;Saini and Singh, 2019b;García-Quismondo and Mena Marugán, 2019;Li et al, 2019;, but also the cosmological perturbations (Agullo, 2018;Castelló Gomar et al, 2020;Li et al, 2020a;Li et al, 2020b).…”
