分歧理论和突变理论-动力系统-V 本书特色
Both bifurcatiotheory and catastrophe theory are studies of smooth systems,tbcusing oproperties that seem manifestly non-smooth. Bifurcations are suddechanges that occur ia system as one or more parameters are varied.Catastrophe theory is accurately described as singularity theory and its applications.
These two theories are important tools ithe study of differential equations and of related physical systems.Analyzing the bifurcations or singularities of a system provides useful qualitative informatioabout its behaviour. The authors have writtethis book with reffeshing clarity.Theexpositiois masterful,with penetrating insights.
