Monographs in Mathematics,1017-0480 ;1083-030-36713-4 Linear relations -- Boundary triplets and Weyl functions -- Spectra and Weyl functions -- Operator models -- Nonnegative selfadjoint extensions -- Sturm-Liouville operators -- Canonical systems -- Schrodinger operators -- Sums of closed subspaces in a Hilbert space -- Factorization of bounded linear operators -- Integral representations of Carathéodory functions -- The integral representation of Nevanlinna functions.This open access book presents a comprehensive survey of modern operator techniques for boundary value problems and spectral theory, employing abstract boundary mappings and Weyl functions. It includes self-contained treatments of the extension theory of symmetric operators and relations, spectral characterizations of selfadjoint operators in terms of the analytic properties of Weyl functions, form methods for semibounded operators, and functional analytic models for reproducing kernel Hilbert spaces. Further, it illustrates these abstract methods for various applications, including Sturm-Liouville operators, canonical systems of differential equations, and multidimensional Schrödinger operators, where the abstract Weyl function appears as either the classical Titchmarsh-Weyl coefficient or the Dirichlet-to-Neumann map. The book is a valuable reference text for researchers in the areas of differential equations, functional analysis, mathematical physics, and system theory. Moreover, thanks to its detailed exposition of the theory, it is also accessible and useful for advanced students and researchers in other branches of natural sciences and engineering.Monographs in Mathematics,1017-0480 ;108Operator theoryDifferential equationsPartial differential equationsSystem theoryOperator Theoryhttps://scigraph.springernature.com/ontologies/product-market-codes/M12139Ordinary Differential Equationshttps://scigraph.springernature.com/ontologies/product-market-codes/M12147Partial Differential Equationshttps://scigraph.springernature.com/ontologies/product-market-codes/M12155Systems Theory, Controlhttps://scigraph.springernature.com/ontologies/product-market-codes/M13070MathematicsOperator theoryDifferential equationsPartial differential equationsSystem theoryOperator theory.Differential equations.Partial differential equations.System theory.Operator Theory.Ordinary Differential Equations.Partial Differential Equations.Systems Theory, Control.515.724Behrndt Jussiauthttp://id.loc.gov/vocabulary/relators/aut321452Hassi Seppoauthttp://id.loc.gov/vocabulary/relators/autde Snoo Henkauthttp://id.loc.gov/vocabulary/relators/autMiAaPQMiAaPQMiAaPQBOOK996418201703316Boundary Value Problems, Weyl Functions, and Differential Operators2172901UNISA01265cam2 22002773 450 SOB00851320250902121834.020040211d1993 |||||ita|0103 baitaIT1. itinerario: [Duomo e Guglia di S.
