Electrically charged regular black holes in higher dimensions: Maxwellian limit, branch point of the Lagrangian, and thermodynamics

Bobir Toshmatov, Bobomurat Ahmedov, Nozima Isamadinova +2

Electrically charged regular black holes in general relativity coupled to nonlinear electrodynamics are known to require a double-valued Lagrangian density $L(F)$, with a branch po…
