Dragomir S.S. Riemann-Stieltjes Integral Inequalities for Complex Functions Defined on Unit Circle-with Applications to Unitary Operators in Hilbert Spaces

Boca Raton: CRC Press, 2019. — 155 p.The main aim of this book is to present several results related to functions of unitary operators on complex Hilbert spaces obtained, by the author in a sequence of recent research papers. The fundamental tools to obtain these results are provided by some new Riemann-Stieltjes integral inequalities of continuous integrands on the complex unit circle and integrators of bounded variation.FeaturesAll the results presented are completely proved and the original references where they have been firstly obtained are mentioned
Intended for use by both researchers in various fields of Linear Operator Theory and Mathematical Inequalities, as well as by postgraduate students and scientists applying inequalities in their specific areas
Provides new emphasis to mathematical inequalities, approximation theory and numerical analysis in a simple, friendly and well-digested manner.
