چکیده انگلیسی
We present a new, very short proof of a conjecture by I. RaÅa, which is an inequality involving basic Bernstein polynomials and convex functions. It was affirmed positively very recently by J. Mrowiec, T. Rajba and S. WÄ
sowicz (2017) by the use of stochastic convex orders, as well as by Abel (2017) who simplified their proof. We give a useful sufficient condition for the verification of some stochastic convex order relations, which in the case of binomial distributions are equivalent to the I. RaÅa inequality. We give also the corresponding inequalities for other distributions. Our methods allow us to give some extended versions of stochastic convex orderings as well as the I. RaÅa type inequalities. In particular, we prove the Muirhead type inequality for convex orders for convolution polynomials of probability distributions.
