Nowadays one knows rather much about \n                \n                \u003ci\u003eL\u003c\/i\u003e\n                                \n                \u003csup\u003e2\u003c\/sup\u003e\n                                -semibounded differential and pseudo-differential operators, although their complete characterization in analytic terms causes difficulties even for rather simple operators. Until recently almost nothing was known about analytic characterizations of semi-boundedness for differential operators in other Hilbert function spaces and in Banach function spaces. The goal of the present book is to partially fill this gap. Various types of semi-boundedness are considered and some relevant conditions which are either necessary and sufficient or best possible in a certain sense are given. Most of the results reported in this book are due to the authors.\n            \n            \u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783319045573\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783319356709\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Hardcover - 9783319045573","offer_id":51309230086,"sku":"9783319045573","price":53.49,"currency_code":"EUR","in_stock":true},{"title":"Softcover - 9783319356709","offer_id":39419990605917,"sku":"9783319356709","price":53.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/f2fa099d-fff5-491b-9643-ae128603221b.jpg?v=1772171872","url":"https:\/\/shop.autorenwelt.de\/products\/semi-bounded-differential-operators-contractive-semigroups-and-beyond-von-alberto-cialdea-vladimir-mazya","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
