\begin{document}$ \sigma, \zeta, \delta, \chi $\end{document}, vector fields \begin{document}$ \omega, \rho $\end{document}, ϕ, and Polyakov fields Φ and \begin{document}$ \bar{\Phi} $\end{document}at finite temperature and chemical potential. Non-extensive effects were introduced through a dimensionless parameter q, and the results were compared to those of the extensive case (\begin{document}$ q\rightarrow 1 $\end{document}). In the non-extensive case, the exponential in the Fermi-Dirac (FD) function was modified to a q-exponential form. The influence of the q parameter on the thermodynamic properties, pressure, energy, and entropy density, as well as trace anomaly, was investigated. The speed of sound and specific heat with non-extensive effects were also studied. Furthermore, the effect of non-extensivity on the deconfinement phase transition as well as the chiral phase transition of \begin{document}$ u, d, $\end{document} and s quarks was explored. We found that the critical end point (CEP), which defines the point in the \begin{document}$ (T - \mu) $\end{document} phase diagram where the order of the phase transition changes, shifts to a lower value of temperature, \begin{document}$T_{\rm CEP}$\end{document}, and a higher value of chemical potential, \begin{document}$\mu_{\rm CEP}$\end{document}, as the non-extensivity is increased, that is, \begin{document}$ q> $\end{document}1."> Thermodynamic properties and phase diagram of quark matter within non-extensive Polyakov chiral <i>SU</i> (3) quark mean field model -
