Abstract: This paper deals with constructing the modified form of the Post‐Widder operators, which reproduce constant and e2ax for fixed a>0 . We discuss the uniform convergence of the constructed operators with the function f .… read more here.

Abstract: In this note, a novel method for parametric inversion of Laplace transforms by means of the Post–Widder formula is developed. In brief, the coefficients of the MacLaurin series equivalent of the sequence, which converges to… read more here.
