The operator is a three variable analogue of the operator given earlier by W. A. Al-Salam [1] and H. B. Mittal [10]. The operator is useful for finding operational representations and generating functions of polynomials of three variables and will be dealt in a separate communication.application/pdfspainfo:eu-repo/semantics/openAccesshttp://creativecommons.org/licenses/by/4.0Differential OperatorsSpecial FunctionsGenerating FunctionsA study on a calculus for the Tk,x,y,z-operatorinfo:eu-repo/semantics/articlehttps://purl.org/pe-repo/ocde/ford#1.01.00
