  The present article aims to introduce a unified family of the Apostol
type-truncated exponential-Gould-Hopper polynomials and to characterize its
properties via generating functions. A unified presentation of the generating
function for the Apostol type-truncated exponential-Gould-Hopper polynomials is
established and its applications are given. By the use of operational
techniques, the quasi-monomial properties for the unified family are proved.
Several explicit representations and multiplication formulas related to these
polynomials are obtained. Some general symmetric identities involving multiple
power sums and Hurwitz-Lerch zeta functions are established by applying
different analytical means on generating functions.
