For such\nequations a KAM-like theorem is     proved, stating that\nsolutions of the unperturbed equation that are         quasiperiodic\nin time mostly persist in the perturbed one. The theorem      is\napplied to classical nonlinear PDE's with one-dimensional\nspace      variable such as the nonlinear string and nonlinear\nSchr|dinger equation andshow that the equations have\n\"regular\" (=time-quasiperiodic and             time-periodic) solutions\nin rich supply.\nThese results cannot be        obtained by other techniques. The\nbook will thus be of interest to          mathematicians and\nphysicists working with nonlinear PDE's.\nAn extensivesummary of the results and of related topics is\nprovided in the             Introduction. All the nontraditional\nmaterial used is discussed in the firstpart of the book and\nin five appendices.\u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Springer\u003c\/p\u003e \u003cp\u003ePublication Date: 1993-11-03\u003c\/p\u003e \u003cp\u003eFormat: Paperback\u003c\/p\u003e \u003cp\u003eISBN-13: 9783540571612\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/BFb0092243\u003c\/p\u003e \u003cp\u003eDimensions: 235cm x155cm\u003c\/p\u003e \u003cp\u003ePages: 104\u003c\/p\u003e ","brand":"Springer Berlin Heidelberg","offers":[{"title":"Default Title","offer_id":45369790070924,"sku":"9783540571612","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9783540571612.jpg?v=1772802921","url":"https:\/\/fh90cf-fv.myshopify.com\/products\/9783540571612","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
