报告摘要：

The weak cosmic censorship conjecture (WCCC) proposed by Penrose plays an essential role for the predictability of the general relativity. Although a rigorous proof is still absent, Wald's gedanken experiments of throwing matter into extremal and near-extremal black holes provide operational demonstration of the WCCC. Based on Sorce-Wald's formulation, we examine the WCCC in three-dimensional (torsional) gravity as well as in four-dimensional higher-derivative gravity. We find that in 3D Einstein gravity and chiral gravity, the WCCC is always holds; while the presence of torsion might cause a naked singularity. For the 4D Einstein-Maxwell theory with high-order corrections, however, the WCCC is always preserved for non-rotating extremal black holes.
