The present paper deals with the approximation properties for exponential functions of general Durrmeyer type operators having the weights of Szász basis functions. Here we give explicit expressions ...

Special functions occupy a central role in mathematical analysis, bridging pure theory and practical application across diverse scientific fields. Their intrinsic properties—such as recurrence ...

We consider repeated independent sampling from one member of an exponential family of probability distributions. The probability that the sample mean of n such observations falls into some set S n is, ...
