{"product_id":"completeness-of-root-functions-of-regular-differential-operators","title":"Completeness of Root Functions of Regular Differential Operators","description":"The precise mathematical investigation of various natural phenomena is an old and difficult problem. This book is the first to deal systematically with the general non-selfadjoint problems in mechanics and physics. It deals mainly with bounded domains with smooth boundaries, but also considers elliptic boundary value problems in tube domains, i.e. in non-smooth domains. This volume will be of particular value to those working in differential equations, functional analysis, and equations of mathematical physics.","brand":"Taylor \u0026 Francis Ltd","offers":[{"title":"Default Title","offer_id":54225935597912,"sku":"9780582236929","price":229.4,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0278\/1295\/4195\/files\/9780582236929_11c9f57a-ed57-41f1-8d08-2c83fcc34951.jpg?v=1769771729","url":"https:\/\/agendabookshop.com\/products\/completeness-of-root-functions-of-regular-differential-operators","provider":"Agenda Bookshop","version":"1.0","type":"link"}
