A note on certain operational representations for the Laguerre polynomials

AbstractSeveral independent proofs are given for certain interesting operational representations for the classical Laguerre polynomials. At least one of the proofs presented for each result is based upon some rather elementary derivative formulas for the Laguerre polynomials, and is markedly different from the proofs given by earlier authors. A (presumably new) finite summation formula for the Laguerre polynomials has emerged naturally in this investigation
