Abstract
This article is an attempt to stress the usefulness of multi-variable special functions by expressing them in terms of the corresponding Lie algebra or Lie group. The problem of framing the 3-variable 2-parameter Hermite polynomials (3V2PHP) into the context of the irreducible representation \( \downarrow _{0,1}\) of \({\mathcal {G}}(0,1)\) is considered. Certain relations involving 3V2PHP \(H_{m}(x,y,z;\nu _{1},\nu _{2})\) are obtained using the approach adopted by Miller. Certain examples involving other forms of Hermite polynomials are derived as special cases. Further, some Volterra integral equations involving the 3V2PHP \(H_{m}(x,y,z;\nu _{1},\nu _{2})\) are also obtained.
