Five Constructions of Permutation Polynomials over \gf(q^2)
Four recursive constructions of permutation polynomials over \gf(q^2) with
those over \gf(q) are developed and applied to a few famous classes of
permutation polynomials. They produce infinitely many new permutation
polynomials over \gf(q^{2^\ell}) for any positive integer with any
given permutation polynomial over \gf(q). A generic construction of
permutation polynomials over \gf(2^{2m}) with o-polynomials over \gf(2^m)
is also presented, and a number of new classes of permutation polynomials over
\gf(2^{2m}) are obtained
