Tight bounds on Poisson tails with applications to SzÃ¡sz-Mirakyan operators

JosÃ© A. Adell, Daniel CÃ¡rdenas-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…

On the rates of pointwise convergence for Bernstein polynomials

JosÃ© A. Adell, Daniel CÃ¡rdenas-Morales, Antonio J. LÃ³pez-Moreno

Let $f$ be a real function defined on the interval $[0, 1]$ which is constant on $(a, b) \subset [0, 1]$ , and let $B_{n} f$ be its associated $n$ th Bernstein polynomial. We prove that, fo…

Strong Converse Inequalities for Bernstein Polynomials with Explicit Asymptotic Constants

We obtain strong converse inequalities for the Bernstein polynomials with explicit asymptotic constants. We give different estimation procedures in the central and non-central regi…
