1. Newton's Theorem on the Nonintegrability of Ovals An algebraic oval in the plane R2 is part of a real algebraic curve (i.e., the zero set of a polynomial), X homeomorphic to a circle. An oval is called nonsingular if it is C 00-diffeomorphic to the circle. An oval is called algebraically integrable if the area of its segment is an algebraic function of the secant line (i.e., there exists a nontrivial polynomial F ( V, a, b, c) which vanishes if V is the area cut by the line ax+ by = c). Fig. 2 An oval is locally algebraically integrable if the area of Newton's Proof. Let us fix a point 0 inside the oval, its segments coincides with an algebraic function in a and a ray with the origin 0. Consider the function on neighborhood of any line (but these functions may be the oval (or, equivalently, on the space of all the rays different for different lines). issuing from the origin), whose value at the point A equals the area of the sector bounded by the fixed ray, the radius OA and the oval, see Fig. 1. If the oval is integrable, this function is algebraic: a sector consists of the segment and a triangle, and the areas of both of these depend algebraically on the point A: this follows from the algebraicity and the integrability of the oval. Let us move the point A along the oval. After any complete cycle, the area of the sector increases by the area bounded by the oval. In particular, for the same point A this function has an infinite number of values which contradicts its algebraicity. Moreover, the same reasoning proves the following Fig. 1 stronger statement.

Such points x form the equal forces, since the areas of these intersections are hyperbolicity set of the surface. This set is a union of proportional to the squares of distances. some connected components of the to the hypersurface (see [ABG]); such components are called hyperbolicity domains. For example, an ellipsoid has one hyperbolicity do­ main, and a two-sheeted -two such do­ mains. A smooth hyperbolic surface given by a polynomial equation F = 0 partitions Rn into the components which we shall call zones. Let us order them according to the minimal number of intersections with the hypersurface of a path connecting a point of a component with a point of a fixed hyperbolicity domain. This hyperbolicity domain will be called the 0-th zone. The standard charge on the hyperbolic surface F = 0 is defined by the form dxfdF (i.e., as the limit of a homogeneous charge between the surfaces F = 0 and F = e with density 1I e and the signs equal to ± 1 depending on the parity of the number of the Fig. 5 corresponding component of the surface).

If the degree of the polynomial-multiplier is m units more than the critical value d - 2, then the potential in the hyperbolicity domain is a polynomial of degree at most m; see [G]. The Newton-Coulomb potential (the attractive power in Rn is proportional to r1-n) may be replaced here by any Green's function Gin Rn- {0}, which is homogeneous of degrees- n (or, for s = n, proportional to the logarithm on any ray) and satisfies the equation G( -x) = ( -l)sG(x) (s being a ).

The motion of a free point (along a straight line on the plane) may be considered as the motion in the zero field of arbitrary degree. Applying Theroem 11, we obtain special orbits of the motion in a central field of an arbitrary degree A on the plane. These orbits are obtained from the straight lines by the mapping wpAw'\ a= 2/(A + 3). In the case of the universal attraction law these special trajectories are parabolas (a = 2). In the general case, the equation of these generalized parabolic orbits in the polar coordinates is ru = seen¢.

UNIMODAL LOG-CONCAVE AND ; POLYA FREQUENCY SEQUENCES IN COMBINATORICS Francesco Brenti (Memoirs of the AMS, Number 413) In recent years, considerable research has focused on applied to any situation in which log-concavity and unimodality unimodal or log-concave sequences that are of combinatorial questions arise. The second part of the book is devoted to interest. Although these two properties have simple definitions, applications to several combinatorial situations, yielding many proving that a sequence is unimodal or log-concave is often a new results and solutions to some problems that had resisted difficult task requiring refined and sophisticated mathematical attack with other techniques. Both parts of the book point to tools from such areas as representation theory, algebraic many conjectures, open problems, and directions for further geometry, or classical analysis. study.

This same dialogue gets repeated the classroom.

Computational Complexity Theory

Juris Hartmanis, Editor L__ _j

Computational complexity theory is the study of the quantitative laws that govern computing. During the last 25 years, this field has grown into a rich mathematical theory. Currently one of the most active research areas in com­ puter science, complexity theory is of considerable interest to mathematicians as well, since some of the key open problems in this field raise basic questions about the nature of mathematics. Many experts in complexity theory believe that, in coming decades, the strongest influence on the development of mathe­ matics will come from the extended use of computing and from concepts and problems arising in computer science.

This volume contains the proceedings of the AMS Short Course on Computa­ tional Complexity Theory, held at the Joint Mathematics Meetings in Atlanta in January 1988. The purpose of the Short Course was to provide an overview of complexity theory and to describe some of the current developments in the field. The papers presented here represent contributions by some of the top experts in this burgeoning area of research.

Contents: Juris Hartmanis, Overview of computational complexity theory Stephen R. Mahaney, The conjecture and sparse sets Ronald V.

What benefits will using TEX bring authors and marketing, promoting, and distributing the book, not publishers? The obvious advantage that typesetting to mention the direct costs of paper, ink, printing, and from TEX has is that the stage of manually rekeying binding. On the other hand, every publisher will be the work by a typesetter is avoided. Thus, there is no concerned to charge what is a reasonable going rate for danger of new errors creeping in (as otherwise they their books no matter what the production costs are, would inevitably do). In turn, this saves the author and to derive a respectable rate of return. Largely, the from having to read one or more sets of proofs, impact of TEX on the price of books will depend on and results too in some savings in money for the each publisher's policy for pricing and printing books publisher (though I shall return to this point later on). and this already varies wildly from one publisher to Book production can also be speeded up by the three another! to four months that typesetting and proof-reading TEX is making every academic publisher sit up and typically take.

NOVEMBER 1989, VOLUME 36, NUMBER 9 1227 Look what's new in Mathematical Surveys and Monographs The Mathematical Smveys and Monographs series is one you're already familiar with. It's been around since 1943, when The Problem of Momenta byJ. A. Shohat andJ. D. Tamarkin was pub­ lished. The series has grown over the years and includes important mathematical monographs that cover a broad spectrum of areas such as function theory, analysis, approximation theory, algebra, and topology. Each of the books is designed to give a survey of the subject and a brief introduction to its recent developments and unsolved problems. The editorial committee••• Victor W. Guillemin M. Susan Montgomery (Chairman) David Kinderlehrer ------...invites you to participate in the development of this classic series by

• consulting them as reference books • using books in this series in your courses • recommending them to your library • submitting manuscripts for publication to begin a standing order to the Director of Publication at the AMS

New and Recent Publications in Mathematical Surveys and Monographs Each new title is exceptional. All are the high quality mathematical publications you've grown to expect in the Mathematical Surveys and Monographs series.

Second, given some sort of Uncertainty. of decomposition of task-level planning into "planning problems", one is immediately driven to ask, What are the algorithms for these problems? Can plans, in general, be computed? How efficiently can planning algorithms Synopses and Reading Lists run? Historically, the nature of these questions has led researchers to apply tools from theoretical computer Planning and Executing Robot Assembly Strategies in science, computational geometry, and algebra. the Presence of Uncertainty (Bruce R. Donald). Research Recently, a great deal of attention has been focused in robot programming attempts to build robot planning on a particular robotics problem, called the find-path, or systems that can function at the task-level. A task-level generalized movers' problem. In this problem, we ask the specification of a robot plan might have the form, · purely kinematic question, can a robot system be moved Put together this disk rotor assembly. The planner is from one configuration to another, without colliding with given geometric models of the parts, and geometric or obstacles? This is a nicely-defined mathematical problem, analytic models of the robot dynamics. Beyond this, the and, after much research, at this point its computational specification, or input to the planner does not mention complexity is precisely known. the specific kinematic and dynamic constraints that the In fact, the neatness of this problem is deceptive, robot must obey; these are determined by the planner so much so that this formal problem has even been using geometrical computation.

An Equal Opportunity/ Affirmative Action Employer. MATHEMATICAL REVIEWS

ASSOCIATE EDITOR

Applications and recommendations are invited for a two-year appointment as an Associate Editor of Mathematical Reviews (MR), to commence no later than the summer of 1990. Appli­ cations will be welcomed from persons taking leave from other positions, and in particular from tenured faculty members who can take leave to come to MR for two years.

The MR office of the American Mathematical Society is located in Ann Arbor, Michigan, not far from the campus of the University of Michigan, and the editors (although employees of the AMS) enjoy many privileges at the university. At present MR employs fourteen mathemati­ cal editors, about ten consultants, and over sixty nonmathematicians. It produces Mathematical Reviews, Current Mathematical Publications, various indexes, the online service MathSci, and MathSci Disc. The responsibilities of an Associate Editor fall primarily in the day-to-day opera­ tions of selecting articles and books suitable for review, classifying these items, assigning them to reviewers, editing the reviews when they are returned, and correcting galley proof. At this time an individual with considerable breadth in applied mathematics is sought (such as in differential equations, optimization, operations research, systems theory, control theory, information theory, etc.). The ability to write good English is essential, and the ability to read mathematics in major foreign languages is important. (The ability to read mathematical articles in Russian or Chinese is especially desirable.)

Persons interested in combining a sabbatical or other leave with a part-time appointment as an Associate Editor should write (or telephone) for further details. The twelve-month salary is negotiable, and will be commensurate with the experience the applicant brings to the position. Salary and fringe benefits are similar to those in universities. Of special importance is a policy providing termination pay of three months full pay for an editor serving full time for two years.

Applications (including curriculum vitae, bibliography, and names and addresses of at least three references) and recommendations should be sent to Dr. R. G. Bartle, Executive Editor, Mathematical Reviews, P. 0. Box 8604, Ann Arbor, MI 48107-8604. (Telephone: 313-996-5255; FAX: 313-996-2916; INTERNET: [email protected].) Persons who may be interested in applying for this position are urged to inquire without delay.

UEDA THEORY: THEOREMS AND PROBLEMS THE METAPLECTIC REPRESENTATION, MPc Amnon Neeman STRUCTURES AND GEOMETRIC (Memoirs of the AMS. Number 415) QUANTIZATION P. L. Robinson and J. H. Rawnsley Ueda explored the question of which algebraic varieties over (Memoirs of the AMS, Number 410) the complex numbers give rise to Stein manifolds. Affines are one obvious example, but there are others. In 1983, Ueda defined an invariant that "measures" the Steinness of a Zariski open subset of a compact complex surface. The purpose of this book is to study this fascinating and mysterious homological invariant by exploring its functoriality properties, variational properties, and higher dimensional generalizations. The author sets Ueda's invariant in the right pairing of vacuum states for positive polarizations.

On the occasion of Mathematics Awareness Week, the Joint Policy Board for Mathematics commissioned the printing of the posters and postcards that were designed to acquaint the public with this year's theme, "Mathematics: Discovering Patterns". Copies are still available of these well-designed objects:

A. Five-color poster, size 16x20 inches, suitable for framing and ideal as a gift. The poster shows a photograph of silicon bronze sculpture by Helaman Ferguson, Umbilic Torus. $5

B. Black and white poster with the Mathematics Awareness Week theme, from Tilings and Patterns, by Branko Griinbaum and G. C. Shephard. $3

C. Set of 20 color postcards, 10 each of two different bronze works by Helaman Ferguson, Torus with Cross Cap, and Alexander's Horned Wild Sphere, Five Bifurcations. $10

D. Set of 20 color postcards, 5 each of four different fractal images. Limited supply from the 1988 Mathematics Awareness Week. $10

Proceeds will be used to start a fund to underwrite the JPBM Communications Award, given the first time in 1988 to James Gleick for his bestseller CHAOS. Your purchase of these postcards and the poster will help promote a better public understanding of mathematics.

Please specify your order, indicating the quantity desired, by using the appropriate letter for that item. Send a check, payable to American Mathematical Society, to:
