Constant-roll inflation field with Tsallis entopic proposal

In this work, we investigate the high-energy era of the universe from the constant-roll condition perspective by taking the Friedmann equation, which is modified by a non-additive Tsallis entropic proposal. In the framework of the observational data, we determine the constant-roll parameter. Under the fixed field condition of the constant-roll parameter, for the wide range of the power-term of the chaotic potentials, $\sim {\varphi }^{n}$ , which involves some string-chaotic potential models, $n=\frac{2}{3}$ , $n=\frac{4}{5}$ , the non-additive (nonextensive) Tsallis parameter is analyzed graphically. The resulting analysis shows that, in addition to a quasi-de Sitter phase, any value of the range $0.5
