Devoted to dynamic inequalities of Hardy type and extensions and generalizations via convexity on a time scale T, this book gives the time scale versions of a wide range of inequalities, following their histories and development. Each section in self-contained and one can see the relationship between the time scale versions.

Researchers in the fields of mathematical modeling, mathematical biology, and population dynamics will be particularly interested in this material.
