On permutation polynomials of prescribed shape. (English) Zbl 1220.11145
Summary: We count permutation polynomials of $$\mathbb F_q$$ which are sums of $$m+1 (\geq 2$$) monomials of prescribed degrees. This allows us to prove certain results about existence of permutation polynomials of prescribed shape.
