We extend two theorems of Krein concerning entire functions of Cartwright class, and give applications for the Bernstein weighted approximation problem. The Krein class and functions of bounded typeWe start with two classical theorems of Krein concerning entire functions.An entire function f belongs to the Cartwright class if f has at most exponential type, that is, ifand the logarithmic integral converges:
