The Autonomous Interest of Society, which are saddle points and the sides of which are separatrices connecting these saddle points. They are structurally unstable, and in this paper we will study the change in the phase portrait due to arbitrary small changes in the right hand sides of these systems. In particular, attention will be

Terence S. Barker (Senior Research Officer)riate Poisson-equation. Such a system can be studied by associating it with dynamical systems in a finite-dimensional phase-space. The finite-dimensional problems are treated in the frame-work of KAM-theory by Birkhoff normalization and averaging techniques. This leads to a classification of possibl

The Serialisation of Books: Macmillan’s English Men of Letters Series and the New BiographyThis is a chapter about the effect of a specific production format — a uniform series — on a genre such as biography, on the author function, and on the biographical subject. It is comparative, and the study is enhanced because the authors in question and their texts are interactive, with publisher, authors, and texts reflexive.
