Tight bounds on Poisson tails with applications to Szász-Mirakyan operators
José A. Adell, Daniel Cárdenas-Morales
We obtain tight bounds on Poisson tails which are easy to handle. A short proof based on the median of the gamma distribution is given. Numerical comparisons with other known estim…

Approximation of discontinuous functions by positive linear operators. A probabilistic approach
José A. Adell, P. Garrancho, F. J. MartÃnez-Sánchez
We obtain approximation results for general positive linear operators satisfying mild conditions, when acting on discontinuous functions and absolutely continuous functions having…
