This\nbook is a self-contained exposition of the subject. A                  braod\nspectrum of results of both analytic and geometric character\nare  presented, and the methods vary accordingly. The main\ntools are the         variational integral method and the extremal\nlength method, both of which   are thoroughly developed here.\nReshetnyak's basic theorem on discreteness   and openness is\nused from the beginning, but the proof by means             of\nvariational integrals is postponed until near the end. Thus,\nthe     method of extremal length is being used at an early\nstage and leads, among  other things, to geometric proofs of\nPicard-type theorems and a defect      relation, which are some\nof the high points of the present book.\u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Springer\u003c\/p\u003e \u003cp\u003ePublication Date: 2011-12-30\u003c\/p\u003e \u003cp\u003eFormat: Paperback\u003c\/p\u003e \u003cp\u003eISBN-13: 9783642782039\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/978-3-642-78201-5\u003c\/p\u003e \u003cp\u003eDimensions: 242cm x170cm\u003c\/p\u003e \u003cp\u003ePages: 213\u003c\/p\u003e ","brand":"Springer Berlin Heidelberg","offers":[{"title":"Default Title","offer_id":44398556119180,"sku":"9783642782039","price":98.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9783642782039.jpg?v=1775709762","url":"https:\/\/lateknightbooks.com\/products\/9783642782039","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
