Zipf Maneuvers: On Non-Reprintable Materials is a work of conceptual protest that challenges the commodification of knowledge in academic publishing, using mathematical and algorithmic techniques to resist institutional control over intellectual labour. In response to the exorbitant fee imposed by corporate publishers to reprint their own work, neuroscientist Germ n Sierra and literary theorist Andrew C. Wenaus devise a radical strategy to bypass the neoliberal logic of access and ownership. As cultural critic and philosopher Steven Shaviro remarks in the introduction to this volume, the project orbits around Zipf's Law, a statistical principle that ranks words by frequency. Sierra and Wenaus deploy a Python algorithm to reorganize their original articles according to Zipfian distributions, alphabetizing and numerically indexing every word. This reorganization produces a fragmented, non-linear data set that resists conventional reading. Each word is assigned a number corresponding to its original position in the text, creating a disjointed, catalogue-like structure. The result is a protest against the corporate financialization of knowledge and a critique of intellectual property laws that restrict access. By transforming their essays into algorithmically rearranged data, Zipf Maneuvers enacts a singular form of resistance, exposing the absurdity of a system that hinders the free circulation of ideas.

Using Duchamp's technique of the 'readymade', Germ n Sierra has transfromed plundered snippets from medival and scientific journals and repurposed them as poetry. The resulting pieces have a glacial autistic beauty reminiscent of the paintings of de Chirico and Carra, and the early writings of J G Ballard.

This book originated from a course given at the Univcrsidad Aut6noma of Madrid in the Spring of 1994 and in the Universidad Complutense of Madrid in 1995. The goal of these courses is to give the non-specialist an introduction to some old and new ideas in the field of strongly correlated systems, in particular the problems posed by the high-1~ superconducting materials. As theoretical physicists, our starting viewpoint to address the problem of strongly correlat­ ed ferlnion systems and related issues of modern condensed matter physics ·is the renormalization group approach applied both to quantU111 field theory and statistical physics. In recent years this has become not only a powerful tool for retrieving the essential physics of interacting systems but also a link between theoretical physics and modern condensed matter physics. Furthermore, once we have this common background for dealing with apparently different prob­ lems, we discuss more specific topics and even phenomenological aspects of the field. In doing so we have tried to make the exposition clear and simple, with­ out entering into technical details but focusing ill the fundamental physics of the phenomena under study. Therefore ,ve expect that our experience ll1ay have some value to other people entering this fascinating field. We have divided these notes into three parts and each part into chapters, which correspond roughly to one or two lectures. Part I, Chaps. 1-2 (A. H. V.

This 1996 book is an introduction to integrability and conformal field theory in two dimensions using quantum groups. The book begins with a brief introduction to S-matrices, spin chains and vertex models as a prelude to the study of Yang–Baxter algebras and the Bethe ansatz. The basic ideas of integrable systems are then introduced, giving particular emphasis to vertex and face models. Special attention is given to explaining the underlying mathematical tools, including braid groups, knot invariants and towers of algebra. The book then goes on to give a detailed introduction to quantum groups as a prelude to chapters on integrable models, two-dimensional conformal field theories and superconformal field theories. The book contains many diagrams and exercises to illustrate key points in the text.
