On Kahane's ultraflat polynomials
Journal of the European Mathematical Society, Tome 11 (2009) no. 3, pp. 627-703
This paper is devoted to the construction of polynomials of almost constant modulus on the unit circle, with coefficients of constant absolute value. In particular, one obtains a much improved estimate for the error term. A major part of this paper deals also with the long-standing problem of the effective construction of ultraflat polynomials.
