Resumen:
In this article, we consider the best polynomial approximation operator defined on an Orlicz-Lorentz space $Lambda_{w,phi}$ generated by an Orlicz function $phi$ and a non-negative continuous weight function $w$. Then we extend the best polynomial approximation operator from $Lambda_{w,phi}$ to $Lambda_{w,phi´}$, where $phi´$ is the derivative function of $phi$. In addition, we establish some properties of the extended best polynomial approximation operator.
