LetˆL be a positive definite bilinear functional on the unit circle defined on P n , the space of polynomials of degree at most n. Then its Geronimus transformation L is defined byˆL(p, q) = L (z − α)p(z), (z − α)q(z) for all p, q ∈ P n , α ∈ C. GivenˆL, there are infinitely many such L which can be described by a complex free parameter. The Hessenberg(More)
