The problem is therefore to find a map \u003ci\u003eφ \u003c\/i\u003eso that it satisfies the pullback equation: \u003ci\u003eφ\u003c\/i\u003e\u003ci\u003e*\u003c\/i\u003e(\u003ci\u003eg\u003c\/i\u003e) = \u003ci\u003ef\u003c\/i\u003e.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eIn more physical terms, the question under consideration can be seen as a problem of mass transportation. The problem has received considerable attention in the cases \u003ci\u003ek \u003c\/i\u003e= 2 and \u003ci\u003ek \u003c\/i\u003e= \u003ci\u003en\u003c\/i\u003e, but much less when 3 ≤ \u003ci\u003ek \u003c\/i\u003e≤ \u003ci\u003en\u003c\/i\u003e–1. The present monograph provides the first comprehensive study of the equation.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eThe work begins by recounting various properties of exterior forms and differential forms that prove useful throughout the book. From there it goes on to present the classical Hodge–Morrey decomposition and to give several versions of the Poincaré lemma. The core of the book discusses the case \u003ci\u003ek \u003c\/i\u003e= \u003ci\u003en\u003c\/i\u003e, and then the case 1≤ \u003ci\u003ek \u003c\/i\u003e≤ \u003ci\u003en\u003c\/i\u003e–1 with special attention on the case \u003ci\u003ek \u003c\/i\u003e= 2, which is fundamental in symplectic geometry. Special emphasis is given to optimal regularity, global results and boundary data. The last part of the work discusses Hölder spaces in detail; all the results presented here are essentially classical, but cannot be found in a single book. This section may serve as a reference on Hölder spaces and therefore will be useful to mathematicians well beyond those who are only interested in the pullback equation.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003ci\u003eThe Pullback Equation for Differential Forms \u003c\/i\u003eis a self-contained and concise monograph intended for both geometers and analysts. The book may serveas a valuable reference for researchers or a supplemental text for graduate courses or seminars.\u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Birkhäuser\u003c\/p\u003e \u003cp\u003ePublication Date: 2011-11-12\u003c\/p\u003e \u003cp\u003eFormat: Hardcover\u003c\/p\u003e \u003cp\u003eISBN-13: 9780817683122\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/978-0-8176-8313-9\u003c\/p\u003e \u003cp\u003eDimensions: 235cm x155cm\u003c\/p\u003e \u003cp\u003ePages: 436\u003c\/p\u003e ","brand":"Birkhäuser Boston","offers":[{"title":"Default Title","offer_id":45378503377036,"sku":"9780817683122","price":125.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9780817683122.jpg?v=1775703861","url":"https:\/\/lateknightbooks.com\/products\/9780817683122","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
