Nonlinear Evolution Equations and Dynamical Systems : Needs 90

<b>Nonlinear Evolution Equations and Dynamical Systems (NEEDS)</b> provides a presentation of the state of the art. But for some exceptions, the contributions are intentionally brief to give only the gist of the methods, proofs, etc. including references to the relevant literature. This gives a handy overview of current research activities. Hence, the book should be equally useful to the senior researcher as well as the colleague just entering the field.
