{"product_id":"symplectic-twist-maps-christophe-gole-9789810205898","title":"Symplectic Twist Maps: Global Variational Techniques","description":"This book concentrates mainly on the theorem of existence of periodic orbits for higher dimensional analogs of Twist maps. The setting is that of a discrete variational calculus and the techniques involve Conley-Zehnder-Morse Theory. They give rise to the concept of ghost tori which are of interest in the dimension 2 case (ghost circles). The debate is oriented somewhat toward the open problem of finding orbits of all (in particular, irrational) rotation vectors.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Christophe Gole\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 9810205899\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9789810205898\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 11\/23\/2001\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 324\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Hardcover\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 1.35lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 8.60h x 6.10w x 0.90d","brand":"Christophe Gole","offers":[{"title":"Hardcover","offer_id":44860495102207,"sku":"9789810205898","price":81.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_a15e1069-9f95-4465-b15c-fb385efd4728.jpg?v=1709136224","url":"https:\/\/www.whiterainbookhouse.com\/products\/symplectic-twist-maps-christophe-gole-9789810205898","provider":"WR Book House","version":"1.0","type":"link"}
