Polynomial approximation in $L_p(R, dμ)$. I
Abstract
Description
Final representation of all those measures $μ$ for which algebraic polynomials are dense in $L_p(R, dμ)$ is found. The weighted analogue of the Weierstrass polynomial approximation theorem and a new version of the M. Krein's theorem about partial fraction decomposition of reciprocal of an entire function are established.
