The bifurcation diagrams of the most important codimension-three cases are studied in detail. The results presented reach the limits of what is currently known on the bifurcation theory of planar vector fields. While the treatment is geometric, special analytical tools using abelian integrals are needed, and are explicitly developed. The rescaling and normalization methods are improved for application here. The reader is assumed to be familiar with the elements of Bifurcation and Dynamical Systems Theory. The book is addressed to researchers and graduate students working in Ordinary Differential Equations and Dynamical Systems, as well as anyone modelling complex multiparametric phenomena.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ INGRAM","offer_id":52146045452561,"sku":"NLS9783540545217","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9783540545217.jpg?v=1757596223"},{"product_id":"equadiff-2003-proceedings-of-the-international-conference-on-differential-equati-book-freddy-dumortier-9789812561695","title":"Equadiff 2003 - Proceedings Of The International Conference On Differential Equations","description":"This comprehensive volume contains the state of the art on ODE's and PDE's of different nature, functional differential equations, delay equations, and others, mostly from the dynamical systems point of view.A broad range of topics are treated through contributions by leading experts of their fields, presenting the most recent developments. A large variety of techniques are being used, stressing geometric, topological, ergodic and numerical aspects.The scope of the book is wide, ranging from pure mathematics to various applied fields. Examples of the latter are provided by subjects from earth and life sciences, classical mechanics and quantum-mechanics, among others.The proceedings have been selected for coverage in:• Index to Scientific \u0026amp; Technical Proceedings® (ISTP® \/ ISI Proceedings)• Index to Scientific \u0026amp; Technical Proceedings (ISTP CDROM version \/ ISI Proceedings)• CC Proceedings — Engineering \u0026amp; Physical Sciences","brand":"WoB","offers":[{"title":"GB \/ NEW \/ INGRAM","offer_id":52451879026961,"sku":"NLS9789812561695","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9789812561695.jpg?v=1759362859"}],"url":"https:\/\/www.worldofbooks.com\/de-ch\/collections\/autor-buecher-von-freddy-dumortier.oembed","provider":"World of Books ","version":"1.0","type":"link"}
