Analytic Versus Algebraic Density of Polynomials

Christian Berg, Brian Simanek, Richard Wellman

We show that under very mild conditions on a measure $I^¼$ on the interval $[0, \infty)$ , the span of ${x^{k}}_{k = n}^{\infty}$ is dense in $L^{2} (I^¼)$ for any $n = 0, 1, \dots$ . We presen…

Algebraic Versus Analytic Density of Polynomials

Brian Simanek, Richard Wellman

We show that under very mild conditions on a measure $I^¼$ on the real line, the span of ${x^{n}}_{n = j}^{\infty}$ is dense in $L^{2} (I^¼)$ for any $j \in N$ . We also present a s…
