Abstract:
For any sufficiently large $n$, the minimal measure of a subset of $[-\pi,\pi]$ on which some nonzero trigonometric polynomial of order $\le n$ gains half of the $L_1$-norm is shown to be $\pi/(n+1)$. A similar result for entire functions of exponential type is established.

Keywords:
trigonometric polynomials, entire functions, extremal problems, $L_1$-norm.
