{"product_id":"b-mary-rose-operator-methods-for-boundary-value-problems-9781107606111","title":"Operator Methods for Boundary Value Problems","description":"Presented in this volume are a number of new results concerning the extension theory and spectral theory of unbounded operators using the recent notions of boundary triplets and boundary relations. This approach relies on linear single-valued and multi-valued maps, isometric in a Krein space sense, and offers a basic framework for recent developments in system theory. Central to the theory are analytic tools such as Weyl functions, including Titchmarsh-Weyl m-functions and Dirichlet-to-Neumann maps. A wide range of topics is considered in this context from the abstract to the applied, including boundary value problems for ordinary and partial differential equations; infinite-dimensional perturbations; local point-interactions; boundary and passive control state\/signal systems; extension theory of accretive, sectorial and symmetric operators; and Calkin's abstract boundary conditions. This accessible treatment of recent developments, written by leading researchers, will appeal to a broad range of researchers, students and professionals.","brand":"Cambridge University Press","offers":[{"title":"Default Title","offer_id":53696744390998,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0925\/5829\/5382\/files\/product_image_9781107606111_1.jpg?v=1794583781","url":"https:\/\/www.momoxbooks.com\/products\/b-mary-rose-operator-methods-for-boundary-value-problems-9781107606111","provider":"momox","version":"1.0","type":"link"}
