The content includes Fréchet differentiation, the implicit function theorem, bifurcation problems, Brouwer degree, Leray-Schauder degree, fixed point theorems, topological degree of cone mappings, the global bifurcation theorem, extremum principles, Ekeland's variational principle, the minimax principle, index, and category.It consists of three chapters: Nonlinear Operators on Banach Spaces, Topological Degree Theory, and Variational Methods. Some examples are given to explain the applications of these theories, and each chapter contains exercises.This is a textbook for graduate students and senior undergraduate students.\u003c\/p\u003e","brand":"Wsp\/Hep","offers":[{"title":"Default Title","offer_id":48872699330795,"sku":"EB_SC1500_F09-05_SIMS","price":118.81,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0758\/4484\/5803\/files\/9789819825813-1.jpg?v=1785766317","url":"https:\/\/kinokuniya.com.sg\/ja\/products\/9789819825813","provider":"Books Kinokuniya Singapore","version":"1.0","type":"link"}
