CAO Hangjie is a current Ph.D. candidate in the School of Philosophy and Social Development at South China Normal University, under the supervision of Professor Xiong Ming. His research focuses on the intersection of logic and abstract algebra, employing group-theoretic tools to investigate the internal structure of logical systems, the transformational properties of reasoning processes, and their mathematical models. He is currently dedicated to studying the symmetry of Boolean systems, using permutation group actions to characterize their invariant properties and reveal the limitations of their expressive power in terms of symmetry. One of his academic papers has been published in the Chinese journal Studies in Logic. He welcomes exchanges and discussions with peers interested in related fields.
