Asymmetric information (the fact that borrowers have better information than their lenders) and its theoretical and practical evidence now forms part of the basic tool kit of every financial economist. It is a phenomenon that has major implications for a number of economic and financial issues ranging from both micro and macroeconomic level - corporate debt, investment and dividend policies, the depth and duration of business cycles, the rate of long term economic growth - to the origin of financial and international crises. Asymmetric Information in Financial Markets aims to explain this concept in an accessible way, without jargon and by reducing mathematical complexity. Using elementary algebra and statistics, graphs, and convincing real-world evidence, the author explores the foundations of the problems posed by asymmetries of information in a refreshingly accessible and intuitive way.

Qualified Types
Theory and Practice

Publication is planned for September 2003 | Paperback | 169 pages | ISBN: 0-521-54326-6

This book describes the use of qualified types to provide a general framework for the combination of polymorphism and overloading. For example, qualified types can be viewed as a generalization of type classes in the functional language Haskell and the theorem prover Isabelle. These in turn are extensions of equality types in Standard ML. Other applications of qualified types include extensible records and subtyping. Using a general formulation of qualified types, the author extends the Damas/Milner type inference algorithm to support qualified types, which in turn specifies the set of all possible types for any term. In addition, he describes a new technique for establishing suitable coherence conditions that guarantee the same semantics for all possible translations of a given term. Practical issues that arise in concrete implementations are also discussed, concentrating in particular on the implementation of overloading in Haskell and Gofer, a small functional programming system developed by the author.

Contents

1. Introduction; 2. Predicates; 3. Type inference for qualified types; 4. Evidence; 5. Semantics and coherence; 6. Theory into practice; 7. Type classes in Haskell; 8. Type classes in Gofer; 9. Summary and future work; 10. Epilogue; Appendix; References; Index.

Quantum Gravity in 2 +1 Dimensions

Publication is planned for October 2003 | Paperback | 290 pages 35 line diagrams | ISBN: 0-521-54588-9


This timely volume provides a broad survey of (2+1)-dimensional quantum gravity. It emphasises the equantum cosmologyf of closed universes and the quantum mechanics of the (2+1)-dimensional black hole. It compares and contrasts a variety of approaches, and examines what they imply for a realistic theory of quantum gravity. General relativity in three spacetime dimensions has become a popular arena in which to explore the ramifications of quantum gravity. As a diffeomorphism-invariant theory of spacetime structure, this model shares many of the conceptual problems of realistic quantum gravity. But it is also simple enough that many programs of quantization can be carried out explicitly. After analysing the space of classical solutions, this book introduces some fifteen approaches to quantum gravity - from canonical quantization in Yorkfs eextrinsic timef to Chern-Simons quantization, from the loop representation to covariant path integration to lattice methods. Relationships among quantizations are explored, as well as implications for such issues as topology change and the eproblem of timef. This book is an invaluable resource for all graduate students and researchers working in quantum gravity.

Euclidian path integrals and quantum cosmology; 11. Lattice methods; 12. The (2+1)-dimensional black hole; 13. Next steps; Appendix A. The topology of manifolds; Appendix B.

Transcendental Aspects of Algebraic Cycles
Proceedings of the Grenoble Summer School, 2001

Publication is planned for March 2004 | Paperback | 290 pages 1 half-tone | ISBN: 0-521-54547-1

This is a collection of lecture notes from the Summer School eCycles Algebriques; Aspects Transcendents, Grenoble 2001f. The topics range from introductory lectures on algebraic cycles to more advanced material. The advanced lectures are grouped under three headings: Lawson (co)homology, motives and motivic cohomology and Hodge theoretic invariants of cycles. Among the topics treated are: cycle spaces, Chow topology, morphic cohomology, Grothendieck motives, Chow-Kunneth decompositions of the diagonal, motivic cohomology via higher Chow groups, the Hodge conjecture for certain fourfolds, an effective version of Norifs connectivity theorem, Beilinson's Hodge and Tate conjecture for open complete intersections. As the lectures were intended for non-specialists many examples have been included to illustrate the theory. As such this book will be ideal for graduate students or researchers seeking a modern introduction to the state-of-the-art theory in this subject.

Keith Devlin Stanford University, Stanford, California, USA

Sets, Functions, and Logic: An Introduction to Abstract Mathematics, Third Edition

Series: Chapman Hall/CRC Mathematics Series Volume: 25

ISBN: 1-58488-449-5
Publication Date: 11/25/2003
Number of Pages: 160

Helps students adopt the difficult new mode of thinking they need to make the transition to the rigor and abstraction of pure mathematics
Incorporates thorough revisions that improve accessibility even further and reflect the new generation of mathematics students
Includes a new introductory chapter on the nature of mathematics: what it is, how it developed, its language, and its purpose
Contains a variety of new exercises

Keith Devlin. You know him. You've read his columns in MAA Online, you've heard him on the radio, and you've seen his popular mathematics books. In between all those activities and his own research, he's been hard at work revising Sets, Functions and Logic, his standard-setting text that has smoothed the road to pure mathematics for legions of undergraduate students.

Now in its third edition, Devlin has fully reworked the book to reflect a new generation. The narrative is more lively and less textbook-like. Remarks and asides link the topics presented to the real world of students' experience. The chapter on complex numbers and the discussion of formal symbolic logic are gone in favor of more exercises, and a new introductory chapter on the nature of mathematics--one that motivates readers and sets the stage for the challenges that lie ahead.

Students crossing the bridge from calculus to higher mathematics need and deserve all the help they can get. Sets, Functions, and Logic, Third Edition is an affordable little book that all of your transition-course students not only can afford, but will actually readcand enjoycand learn from.
