Thi Kim Thoa Thieu,Roderick Melnikon are uniformly bounded in [-1, 1] then for every .∈ .[-1, 1] and . > 0 there exists a sequence of polynomials ϕ. of degree ≤ .(l+.) (. ∈ N) which interpolates . at the points .. and it tends to . uniformly in [-1, 1]. The weighted versions of this result were proved in [19] and [18] using Freud-ty

The preservation properties of Mache operators lead to qualitative properties of the solution of the associated Cauchy problem. A new Chernoff type approach to the semigroup is presented, as well as quantitative results related to it.
