Chaotic elections! : a mathematician looks at voting by D Saari( Book )

12 editions published in 2001 in English and held by 560 WorldCat member libraries worldwide

"This book shows how mathematics can help to identify and characterize a disturbingly large number of paradoxical situations that result from the choice of a voting procedure. Moreover, rather than being able to dismiss them as anomalies, the likelihood of a dubious election result is suprisingly large. These consequences indicate that election outcomes - whether for president, the site of the next Olympics, the chair of a university department, or a prize winner - can differ from what the voters really wanted. They show that by using an inadequate voting procedure, we can, inadvertently, choose badly. To add to the difficulties, it turns out that the mathematical structures of voting admit several strategic opportunities, which are described." "Finally, mathematics also helps identify positive results: By using mathematical symmetries, we can identify what the phrase "what the voters really want" might mean and obtain a unique voting method that satisfies these conditions." "Saari's book is for anyone who wants to understand not only what happened in the presidential election of 2000, but also how we can avoid similar problems from appearing anytime any group is making a choice using a voting procedure. Reading this book requires little more than high school mathematics and an interest in how the apparently simple situation of voting can lead to surprising paradoxes."--Jacket
Decisions and elections : explaining the unexpected by D Saari( Book )

17 editions published between 2001 and 2011 in English and held by 518 WorldCat member libraries worldwide

It is not uncommon to be frustrated by the outcome of an election or a decision in voting, law, economics, engineering, and other fields. Does this 'bad' result reflect poor data or poorly informed voters? Or does the disturbing conclusion reflect the choice of the decision/election procedure? Nobel Laureate Kenneth Arrow's famed theorem has been interpreted to mean 'no decision procedure is without flaws'. Similarly, Nobel Laureate Amartya Sen dashes hope for individual liberties by showing their incompatibility with societal needs. This highly accessible book offers a new, different interpretation and resolution of Arrow's and Sen's theorems. Using simple mathematics, it shows that these negative conclusions arise because, in each case, some of their assumptions negate other crucial assumptions. Once this is understood, not only do the conclusions become expected, but a wide class of other phenomena can also be anticipated
Geometry of voting by D Saari( Book )

14 editions published between 1994 and 2012 in English and Spanish and held by 412 WorldCat member libraries worldwide

Over two centuries of theory and practical experience have taught us that election and decision procedures do not behave as expected. Instead, we now know that when different tallying methods are applied to the same ballots, radically different outcomes can emerge, that most procedures can select the candidate, the voters view as being inferior, and that some commonly used methods have the disturbing anomaly that a winning candidate can lose after receiving added support. A geometric theory is developed to remove much of the mystery of three-candidate voting procedures. In this manner, the spectrum of election outcomes from all positional methods can be compared, new flaws with widely accepted concepts (such as the "Condorcet winner") are identified, and extensions to standard results (e.g. Black's single-peakedness) are obtained. Many of these results are based on the "profile coordinates" introduced here, which makes it possible to "see" the set of all possible voters' preferences leading to specified election outcomes. Thus, it now is possible to visually compare the likelihood of various conclusions. Also, geometry is applied to apportionment methods to uncover new explanations why such methods can create troubling problems
Basic geometry of voting by D Saari( Book )

14 editions published in 1995 in English and German and held by 380 WorldCat member libraries worldwide

A surprise is how the complexities of voting theory can be explained and resolved with the comfortable geometry of our three-dimensional world. This book is directed toward students and others wishing to learn about voting, experts will discover previously unpublished results. As an example, a new profile decomposition quickly resolves two centuries old controversies of Condorcet and Borda, demonstrates, that the rankings of pairwise and other methods differ because they rely on different information, casts series doubt on the reliability of a Condorcet winner as a standard for the field, makes the famous Arrow`s Theorem predictable, and simplifies the construction of examples. The geometry unifies seemingly disparate topics as manipulation, monotonicity, and even the apportionment issues of the US Supreme Court
Disposing dictators, demystifying voting paradoxes : social choice analysis by D Saari( Book )

16 editions published in 2008 in English and held by 340 WorldCat member libraries worldwide

"We decide by elections, but do we elect who the voters really want? The answer, as we have learned over the past two centuries, is "not necessarily." That is a negative, frightening assertion about a principal tool of democracy! This negativism has been supported by two hundred years of published results showing how bad the situation can be. This expository, largely nontechnical book is the first to find positive results showing that the situation is not nearly as dire and negative as we have been led to believe. Instead there are surprisingly simple explanations for the negative assertions, and positive conclusions can be obtained."--Jacket
Hamiltonian dynamical systems : proceedings of the AMS-IMS-SIAM joint summer research conference held June 21-27, 1987 with support from the National Science Foundation by AMS-IMS-SIAM Joint Summer Research Conference in the Mathematical Sciences on Hamiltonian Dynamical Systems( Book )

Collisions, rings, and other Newtonian N-body problems by D Saari( Book )

10 editions published in 2005 in English and held by 278 WorldCat member libraries worldwide

The fourth chapter analyzes collisions, while the last chapter discusses the likelihood of collisions and other events."--Jacket
Hamiltonian dynamics and celestial mechanics : a Joint Summer Research Conference on Hamiltonian Dynamics and Celestial Mechanics, June 25-29, 1995, Seattle, Washington by Joint Summer Research Conference on Hamiltonian Dynamics and Celestial Mechanics( Book )

19 editions published between 1995 and 2012 in English and held by 260 WorldCat member libraries worldwide

This book contains selected papers from AMS-IMS-SIAM Joint Summer Research Conference on Hamiltonian Systems and Celestial Mechanics held in Seattle in June 1995. The symbiotic of these two topics creates a natural combination for a conference on dynamics. Topics covered include twist maps, the Aubrey-Mather theory, Arnold diffusion, qualitative and topological studies of systems, and variational methods, as well as specific topics such as Melnikov's procedure and the singularity properties of particular systems. As one of the few books that addresses both Hamiltonian systems and celestial mechanics, this volume offers emphasis on new issues and unsolved problems. Many of the papers give new results, yet the editors purposely include some exploratory papers based on numerical computations, a section on unsolved problems, and papers that pose conjectures while developing what is known

Mathematics motivated by the social and behavioral sciences by D Saari( Book )

6 editions published between 2017 and 2018 in English and Undetermined and held by 97 WorldCat member libraries worldwide

"The mathematics needed to advance the social and behavioral sciences most surely differs from what has proved to be successful for the physical sciences. This book addresses the need to develop appropriate mathematical tools that, rather than designed for exactness, reflect the current status for much of the social and behavioral science, which requires qualitative predictors"--
