An investigation of inflationary and bounce cosmology within the context of f(Q) gravity

Abstract

In this work, we have examined the metric affine-based geometric model [Formula: see text] to investigate inflationary cosmology and bouncing cosmology. The four bouncing models we have examined are the exponential, matter, symmetric and super-bounce models. Furthermore, in the inflationary situation, we have employed a scalar field to test whether or not kinetic energy is dominated and whether or not all of the bouncing models are consistent with inflationary conditions. We have investigated various energy conditions for various scale factors and verified whether or not these scale factors are consistent with inflationary scenarios within the framework of inflationary cosmology under [Formula: see text]. In the end, we have shown that the bouncing scale factor under the polynomial model ([Formula: see text]) of [Formula: see text] gravity in a single scalar field is compatible with the inflationary scenario.
