Geometric Cosmology—and in particular Geometric Inflation (GI)—provides a higher-curvature mechanism capable of producing an accelerated expansion in the early Universe without invoking an inflaton in its minimal realization. However, the minimal GI framework does not, by itself, provide a robust mechanism to transfer the energy driving inflation into standard particles and radiation, i.e., it lacks a well-controlled reheating stage leading to a conventional hot Big Bang era. This motivates extending the theory by incorporating a scalar-field sector and explicit interactions with radiation, and then assessing both the background dynamics and the perturbative viability of the resulting scenario.
