Characterization of Multivariate Permutation Polynomials in Positive Characteristic
Pablo A. Acosta-Solarte, Víctor S. Albis · São Paulo Journal of Mathematical Sciences · 2009
Multivariate permutation polynomials over the algebra of formal series over a finite field and its residual algebras are characterized. Some known properties of permutation polynomials over finite fields are also extended.AMS Classification 2000: 13B25, 13F25, 11T55. Keywords: Multivariate permutation polynomials.
