Resumo: t is said that von Neumann once referred to nonlinear theory as a theory of non-elephants. A similar remark is credited to Stanislav Ulan. These stories illustrate a common problem with nonlinear models: the subject is so vast that it is difficult to formulate general theories similar to those existing for linear models. bNon-elephantsQ are everything: giraffes, crabs, plants, basalt rocks, thoughts, planets and even statisticians... How could we have a theory for so diverse a subjects?.
