It explains some conditions to prove some Frobenius?Schur decompositions for linear relations and characterizes the stability of the essential spectra of these linear relations. It focuses on the study of the Fredholm theory in both Banach and Hilbert spaces, the local spectral theory of multivalued linear operators and the block matrix of linear relations. As a pioneering literature discussing spectral theory of bounded and unbounded block matrices of linear relations, this book attempts to contribute to the scarce literature on the topic. It gathers the minimum needed background material which allows a relatively friendly access to the book. Detailed proofs of all theorems are exhibited with accuracy and clarity, allowing students to thoroughly familiarize themselves with all the basic concepts. 410 0$aInfosys Science Foundation Series in Mathematical Sciences,$x2364-4044 606 $aOperator theory 606 $aOperator Theory 615 0$aOperator theory. 615 14$aOperator Theory. 676 $a515.724 700 $aAmmar$b Aymen$01853398 701 $aJeribi$b Aref$0755592 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9911034939803321 996 $aSpectral Theory of Block Multivalued Operator Matrices$94449507 997 $aUNINA
