| contents | To address the singularity problem in black hole physics, Penrose proposed the cosmic censorship conjecture . However, whether this conjecture holds in different types of black holes, especially for the Strong Cosmic Censorship Conjecture (SCCC), remains an issue worth further exploration. This study investigates the Yang-Mills field modified RN black hole, which provides new possibilities for exploring the Strong Cosmic Censorship Conjecture due to its unique nonlinear dynamical properties. In this work, the perturbation equations of two scalar fields for the Yang-Mills field modified RN black hole are derived. By combining the WKB method and the Prony method, the quasi-normal modes frequencies of the perturbations are analyzed. Additionally, constraints on the charge-to-mass ratio of the charged and massive scalar field are obtained using the Weak Gravity Conjecture (WGC), and it is shown that the Yang-Mills field modified RN black hole satisfies the SCCC conditions in the extreme state. The study reveals that the Yang-Mills field charge $q_{YM}$ significantly affects the damping effect and gravitational blueshift effect of the perturbations, causing the RN black hole in the extreme state to transition from violating the SCCC to satisfying it. Furthermore, when the charge-to-mass ratio $q/m$ of the charged and massive scalar field satisfies the WGC condition, the scalar field perturbations destabilize the Cauchy horizon of the Yang-Mills field modified RN black hole in the extreme state, thus confirming the applicability of the SCCC under extreme conditions. This study highlights the key role of nonlinear fields in singularity theory and gravitational dynamics, providing important support for the completeness of general relativity and offering new insights into the theoretical research of black holes in extreme states. |
