Abstract
In this paper, the authors define Sherman's functional deduced from Sherman's inequality. They establish lower and upper bounds for Sherman's functional and study its properties. As consequences of the main results, they obtain new bounds for Csiszár $f$-divergence functionals and, as special cases, bounds for Shannon's entropy. As applications, the authors use the Zipf-Mandelbrot law to introduce a new entropy and to derive some related results.
