We use an operational method to show that Legendre polynomials can be viewed as discrete convolutions of Laguerre polynomials. It is furthermore shown that they can be derived as a particular case of a new family of two-variable orthogonal polynomials, whose properties are studied with some details. It is furthermore shown that this point of view allow the derivation of new properties of Legendre polynomials and it is also shown how it can be extended to the Jacobi family.

Abstract
We use an operational method to show that Legendre polynomials can be viewed as discrete convolutions of Laguerre polynomials. It is furthermore shown that they can be derived as a particular case of a new family of two-variable orthogonal polynomials, whose properties are studied with some details. It is furthermore shown that this point of view allow the derivation of new properties of Legendre polynomials and it is also shown how it can be extended to the Jacobi family.File in questo prodotto:
