摘要：In this talk, we propose  some new  algebraic structures of  permutation polynomials (PPs) over  finite fields.  As two applications of these new algebraic structures, we give some classes of new PPs over  finite fields and answer an open problem raised by Charpin and  Kyureghyan in their paper [Finite Fields Appl. 15 (2009), no. 5, 615-632], and we improve some results of Ding and Zieve. This talk is based on the results in [P. Yuan, Algebraic Structure of Permutational Polynomials over  finite fields, Commun Algebra, DOI: 10.1080/00927872.2025.2476727]
