On 2‐orthogonal polynomials of Laguerre type
On 2‐orthogonal polynomials of Laguerre type
Let be a sequence of 2‐orthogonal monic polynomials relative to linear functionals ω 0 and ω 1 (see Definition 1.1). Now, let be the sequence of polynomials defined by . When is, also, 2‐orthogonal, is called “classical” (in the sense of having the Hahn property). In this case, both and …
