The approximation of functions by linear positive operators is an important research topic in general mathematics and it also provides powerful tools to applica

To date, the theoretical development of q-calculus has rested on a non-uniform basis. Generally, the bulky Gasper-Rahman notation was used, but the published wo

This pioneering book presents a study of the interrelationships among operator calculus, graph theory, and quantum probability in a unified manner, with signifi

Simply put, quantum calculus is ordinary calculus without taking limits. This undergraduate text develops two types of quantum calculi, the q-calculus and the h

The Malliavin calculus was developed to provide a probabilistic proof of Hormander's hypoellipticity theorem. The theory has expanded to encompass other signifi
