Thermodynamic product relations for generalized regular black hole (Q1681915)

Summary: We derive thermodynamic product relations for four-parametric regular black hole (BH) solutions of the Einstein equations coupled with a nonlinear electrodynamics source. The four parameters can be described by the mass (\(m\)), charge (\(q\)), dipole moment (\(\alpha\)), and quadrupole moment (\(\beta\)), respectively. We study its complete thermodynamics. We compute different thermodynamic products, that is, area product, BH temperature product, specific heat product, and Komar energy product, respectively. Furthermore, we show some complicated function of horizon areas that is indeed \textit{mass-independent} and could turn out to be \textit{universal}.
