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, ...

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 ...

Matrix functions, such as the exponential, square root and cosine, play an indispensable role in various fields including quantum mechanics, control theory and numerical solution of differential ...
