{"product_id":"hormander-operators-marco-bramanti-9789811261688","title":"Hormander Operators","description":"Hmander operators are a class of linear second order partial differential operators with nonnegative characteristic form and smooth coefficients, which are usually degenerate elliptic-parabolic, but nevertheless hypoelliptic, that is highly regularizing. The study of these operators began with the 1967 fundamental paper by Lars Hmander and is intimately connected to the geometry of vector fields.Motivations for the study of Hmander operators come for instance from Kolmogorov-Fokker-Planck equations arising from modeling physical systems governed by stochastic equations and the geometric theory of several complex variables. The aim of this book is to give a systematic exposition of a relevant part of the theory of Hmander operators and vector fields, together with the necessary background and prerequisites.The book is intended for self-study, or as a reference book, and can be useful to both younger and senior researchers, already working in this area or aiming to approach it.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Marco Bramanti, Luca Brandolini\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 9811261687\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9789811261688\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e World Scientific Publishing Company\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 12\/27\/2022\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 724\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Hardcover\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 2.96lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.61h x 6.69w x 1.50d","brand":"Marco Bramanti","offers":[{"title":"Hardcover","offer_id":44129321353471,"sku":"9789811261688","price":199.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_17512a20-f730-4838-9b02-536866b36cd9.jpg?v=1687463252","url":"https:\/\/www.whiterainbookhouse.com\/products\/hormander-operators-marco-bramanti-9789811261688","provider":"WR Book House","version":"1.0","type":"link"}
