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: A distinguished class of polyhedral cones is considered. For a linear operator $$\mathcal {L}$$L preserving a cone in this class, we prove, under some assumption on the number of edges of the cone, that its… read more here.
