Nowadays one knows rather much about \u003ci\u003eL\u003c\/i\u003e\u003csup\u003e2\u003c\/sup\u003e-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.\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Rarewaves","offers":[{"title":"Default Title","offer_id":58041528385910,"sku":"9783319045573","price":53.03,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0092\/7504\/8033\/files\/orig_26230242.jpg?v=1780894491","url":"https:\/\/www.rarewaves.com\/products\/9783319045573-semi-bounded-differential-operators-contractive-semigroups-and-beyond","provider":"Rarewaves.com","version":"1.0","type":"link"}
