Abstract | With the aid of multivariate Sheer-type polynomials and dierential operators, this paper provides two kinds of general expansion formulas, called respectively the first expansion formula and the second expansion formula, that yield a constructive solution to the problem of the expansion of $A(\hat{t})f\widehat{(g(t))}$ (a composition of any given formal power series) and the expansion of the multivariate entire functions in terms of multivariate Sheer-type
polynomials, which may be considered an application of the first expansion formula and the Sheer-type operators. The results are
applicable to combinatorics and special function theory.
