Abstract
In this work, we obtain the approximation properties of a new generalization
of Szász-Mirakjan operators based on post-quantum calculus. Firstly, for
these operators, a recurrence formulation for the moments is obtained, and up to the fourth degree, the central
moments are examined. Then, a local approximation result is attained. Furthermore, the degree of
approximation in respect of the modulus of continuity on a finite closed
set and the class of Lipschitz are
computed. Next, the weighted uniform approximation on an unbounded interval
is showed, and by the modulus of continuity, the order of convergence
is estimated. Lastly, we proved the Voronovskaya type theorem and gave some illustrations to compare the related operators' convergence to a certain function.
