These techniques allow for the solution of problems that may be difficult to treat. Specifically, 2×2 operator matrices yield significant mathematical inequalities in various fields of operator theory and matrix analysis. The authors employ block matrices to simplify complicated problems. Operator matrices have garnered attention for their applications in quantum information and computing theories. Each chapter concludes with a diverse set of exercises and problems for readers, along with references to relevant literature. Some problems pose open questions, while others challenge readers and provide suggestions for future research. This book is suitable for an advanced undergraduate or graduate course and can be used in the classroom. It also serves as a valuable resource for researchers and students in mathematics and physics who have a basic understanding of linear algebra, functional analysis, and operator theory.Frontiers in Mathematics,1660-8054Operator theoryOperator TheoryOperator theory.Operator Theory.512.9434Moslehian Mohammad Sal1966-1846345Osaka HiroyukiMiAaPQMiAaPQMiAaPQBOOK9910886065703321Advanced Techniques with Block Matrices of Operators4430650UNINA
