Smooth polynomial expansions of piecewise-differentiable functions. (English) Zbl 0721.41043

Summary: This paper proposes an extension of the expansions of analytic functions in the \(A_ n\) polynomials defined by G. Adomian [Nonlinear stochastic operator equations (1986; Zbl 0609.60072)] to consider piecewise-differentiable functions.
