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]
