Abstract:
We study a family of the Laurent biorthogonal polynomials arising from the Hermite continued fraction for a ratio of two complete elliptic integrals. Recurrence coefficients, explicit expression and the weight function for these polynomials are obtained. We construct also a new explicit example of the Szegő polynomials orthogonal on the unit circle. Relations with associated Legendre polynomials are considered.
Keywords:
Laurent biorthogonal polynomials; associated Legendre polynomials; elliptic integrals.
