Linear operator equations arise in both mathematical theory and engineering practice. The norm estimates suggested in the book have applications to the theories of ordinary differential, difference, functional-differential and integro-differential equations, as well as to the theories of integral operators and analytic functions. This book provides new tools for specialists in matrix theory and functional analysis. A significant part of the book covers the theory of triangular representations of operators that was developed by L de Branges, M S Brodskii, I C Gohberg, M G Krein, M S Livsic and other mathematicians.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ GARDNERS","offer_id":49737815064849,"sku":"NGR9789813221260","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"GB \/ NEW \/ INGRAM","offer_id":52481930789137,"sku":"NLS9789813221260","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9813221267.jpg?v=1751160665"},{"product_id":"norm-estimations-for-operator-valued-functions-and-their-applications-book-michael-gil-9780824796099","title":"Norm Estimations for Operator Valued Functions and Their Applications","description":"Intended for specialists in functional analysis and stability theory, this work presents a systematic exposition of estimations for norms of operator-valued functions, and applies the estimates to spectrum perturbations of linear operators and stability theory.
