This study investigates the topological classification of critical points of black holes in 4D Einstein-Gauss-Bonnet gravity coupled to Born-Infeld theory. Born-Infeld corrections affect the topological charge of critical points of the charged AdS black hole system independently, while Gauss-Bonnet corrections do not. However, the topological charge of the Einstein-Gauss-Bonnet theory remains unchanged in the presence of Born-Infeld coupling in the combined system.
The topological classification of critical points of black holes in 4D Einstein-Gauss-Bonnet gravity coupled to Born-Infeld theory is investigated. Considered independently, Born-infeld corrections to the Einstein action alter the topological charge of critical points of the charged AdS black hole system, whereas the Gauss-Bonnet corrections do not. For the combined system though, the topological charge of the Einstein -Gauss-Bonnet theory is unaltered in the presence of Born-Infeld coupling. (C) 2022 The Author(s). Published by Elsevier B.V.
