A Note on a Three Variables Analogue of Bessel Polynomials

These polynomials were introduced by them in connection with the solution of the wave equation in spherical coordinates. They are the polynomial solutions of the differential equation. x 2 y (x) + (ax + b) y (x) = n (n + a - 1) y (x) Abstract: The present paper deals with a study of a three variables analogue of Bessel polynomials. Certain representations, a Schlafli's contour integral, a fractional integral, Laplace transformations, some generating functions and double and triple generating functions have been obtained.
