Recently, the investigation of the topological classes of black holes with two different methods has attracted the attention of researchers with respect to the existence of critical points, which is an important structure in the phase diagram of a thermodynamic system. One of these methods the examination of the topological classes of black holes with the help of Duan’s topological current φ-mapping theory. Therefore, we consider three different types of black holes, i.e., Hayward-AdS black holes, quintessential Hayward-AdS black holes, and AdS Hayward black holes in Einstein-Gauss-Bonnet gravity. Then we will explore their thermodynamic topological classes. The interesting point to note in our studies was that, unlike previous studies, all of our black holes have the same topological class, and the addition of quintessence or GB terms, etc., or dimensions do not change the topological numbers In the end, we compare the thermodynamic topological class of our black holes with other black holes investigated in the literature.
