N2 - Results of Chebyshev and Bernstein about polynomials with the smallest deviation from zero in a weighted norm are extended to entire functions of exponential type. Suppose that a function ρm belongs to the Cartwright class, is of type m, and is positive on the real axis. Let σ≥m. Functions that have the smallest deiation from zero among the entire functions of type σ are constructed in the uniform and integral metrics.
