Our investigation centers on the semi-classical regime. Specifically, we derive the GUP-modified versions of the Friedmann, Raychaudhuri, and Klein–Gordon equations. Subsequently, we conduct a systematic analysis of the qualitative dynamics for the potential V(ϕ)=V0sinh−n(μϕ). This involves formulating an autonomous dynamical system using suitable dynamical variables, followed by a qualitative analysis through linear stability theory. Our findings reveal that incorporating GUP markedly alters the fixed points compared to the scenario without quantum effects, where GUP is not considered.Physics and AstronomyArticleSCOPUS10.1016/j.aop.2024.1698952-s2.0-852132920031096035X
