Abstract
Given a symmetric Sobolev inner product of order N, the corresponding sequence
of monic orthogonal polynomials {Qn} satisfies that Q2n(x) = Pn(x2), Q2n+1(x) =
xRn(x2) for certain sequences of monic polynomials {Pn} and {Rn}. In this paper, we
deduce the integral representation of the inner products such that {Pn} and {Rn} are
the corresponding sequences of orthogonal polynomials. Moreover, we state a relation
between both inner products which extends the classical result for symmetric linear
functionals.
Key words: Sobolev inner product, orthogonal polynomials, symmetrization
process.
