$\lambda$-Griffiths polynomials: Bispectrality and biorthogonality

N. Crampe, L. Frappat, J. Gaboriaud +3

We introduce a generalization of bivariate Griffiths polynomials depending on an additional parameter $\lambda$. These $\lambda$-Griffiths polynomials are bivariate, bispectral and biorthogona…
