Construction of Permutation Polynomials of Certain Specific Cycle Structure over Finite Fields

Abstract

For a finite field of odd number of elements we construct families of permutation binomials and permutation trinomials with one fixed-point (namely zero) and remaining elements being permuted as disjoint cycles of same length. Binomials and trinomials providing permutations with cycles of many lengths with certain frequency are also constructed.Comment: 10 pages, 1 table, Comments welcom
