Geronimus transformations for sequences of $d$-orthogonal polynomials (1905.08746v1)

Abstract: In this paper an extension of the concept of Geronimus transformation for sequences of $d$-orthogonal polynomials ${P_n}$ is introduced. The transformed sequences ${P^{(k)}_n}$, for $ k=1,\ldots, d,$ are analyzed and some relationships between these new sequences of polynomials are given. Also the associated Hessenberg matrices and their transformed are studied.
