Motivated by recent results on the constructions of permutation polynomials with few terms over the finite field F2n, where n is a positive even integer, we focus on the construction of permutation trinomials over F2n
Nearby in the stack
from Niho exponents. As a consequence, several new classes of permutation trinomials over
F2n
are constructed from Niho exponents based on some subtle manipulation of solving equations with low degrees over finite fields.
