Resumen

Given a nontrivial positive measure φ (i.e., a Borel measure with infinite support), we say that {Pn (x)}∞ n=0 is the sequence of monic orthogonal polynomials on the real line (MOPRL, in short) associated with φ, if Pn (x) is a monic polynomial of degree n satisfying xj Pn (x)dφ(x) = δn,j ρn , 0 ≤ j ≤ n, (1) R where δn,j is the Kronecker delta and ρn ̸= 0 for n ≥ 0.
