Qısa məlumat

In this article, by using the notion of quantum calculus, we define a new type Szasz-Mirakjan operators based on the q-integers. We derive a recurrence formula and calculate the moments Phi(n,q)(t(m); X) for m=0,1,2 and the central moments Phi(n,q)((t-x)(m);X) for m=1,2. We give estimation for the first and second-order central moments. We present a Korovkin type approximation theorem and give a local approximation theorem by using modulus of continuity. We obtain a local direct estimate for the new Sz & aacute;sz-Mirakjan operators in terms of Lipschitz-type maximal function of order alpha. Finally, we prove a Korovkin type weighted approximation theorem.
