Understanding, finding, or even deciding on the existence of real solutions to a system of equations is a difficult problem with many applications outside of mathematics. While it is hopeless to expect much in general, we know a surprising amount about these questions for systems which possess additional structure often coming from geometry. This book focuses on equations from toric varieties and Grassmannians. Not only is much known about these, but such equations are common in applications. There are three main themes: upper bounds on the number of real solutions, lower bounds on the number of real solutions, and geometric problems that can have all solutions be real. The book begins with an overview, giving background on real solutions to univariate polynomials and the geometry of sparse polynomial systems. The first half of the book concludes with fewnomial upper bounds and with lower bounds to sparse polynomial systems. The second half of the book begins by sampling some geometric problems for which all solutions can be real, before devoting the last five chapters to the Shapiro Conjecture, in which the relevant polynomial systems have only real solutions.

Kathy Ireland communicates with moms every day: online, at the grocery store, at church, at speaking engagements, and on her company website. She is grateful that her conversations don't center around beauty tips or requests for autographs or advice on how to dress. Rather, she has the honor of hearing from real women who struggle with balancing the responsibilities of marriage, raising children, managing a household or career or both, and finding any time left to take care of themselves. As the involved mom of three very active children, the supportive wife of an emergency room doctor, and a dynamic businesswoman, Kathy knows of these struggles firsthand. She credits her strong faith in God and her parents' love and support for any success she has today and dedicates her days to finding the solutions that can make life easier for busy moms in all phases of life. As she tackles the tough financial concerns families feel today and many other issues, Kathy offers empathy and encouragement. She shares stories from her own life and wisdom she has gained through her years from teenager with a paper route to successful supermodel to mom to entrepreneur with a dream for big business big business which was realized by building what Forbes now calls the "Billion Dollar Brand."

Real People, Real Problems, Real Solutions offers a clear introduction to psychoanalytic practice from a Kleinian perspective and shows how the modern Kleinian works with the most taxing and least conforming of their patients. Illustrated by extensive case material this book: *reviews Freud's original theoretical concepts and examines Klein's contributions to the field of psychoanalysis, clarifying and comparing the two approaches in the clinical setting. *identifies and explores who makes up the psychoanalyst's most challenging case load and demonstrates how the Kleinian psychoanalytic approach is helpful to these individuals. *discusses the current state of traditional methods of training at psychoanalytic institutes, which are shown to be in need of renewal and critical restructuring. Real People, Real Problems, Real Solutions shows how the average psychoanalyst and psychotherapist face many difficult patients in a typical days work. Together with its questioning of what really constitutes psychoanalytic therapy, this is a refreshing read for all practising and training psychoanalysts and psychotherapists.

This book is a guide to concepts and practice in numerical algebraic geometry ? the solution of systems of polynomial equations by numerical methods. Through numerous examples, the authors show how to apply the well-received and widely used open-source Bertini software package to compute solutions, including a detailed manual on syntax and usage options. The authors also maintain a complementary web page where readers can find supplementary materials and Bertini input files. Numerically Solving Polynomial Systems with Bertini approaches numerical algebraic geometry from a user's point of view with numerous examples of how Bertini is applicable to polynomial systems. It treats the fundamental task of solving a given polynomial system and describes the latest advances in the field, including algorithms for intersecting and projecting algebraic sets, methods for treating singular sets, the nascent field of real numerical algebraic geometry, and applications to large polynomial systems arising from differential equations. Those who wish to solve polynomial systems can start gently by finding isolated solutions to small systems, advance rapidly to using algorithms for finding positive-dimensional solution sets (curves, surfaces, etc.), and learn how to use parallel computers on large problems. These techniques are of interest to engineers and scientists in fields where polynomial equations arise, including robotics, control theory, economics, physics, numerical PDEs, and computational chemistry.

Based on a translation of the 6th edition of Gewöhnliche Differentialgleichungen by Wolfgang Walter, this edition includes additional treatments of important subjects not found in the German text as well as material that is seldom found in textbooks, such as new proofs for basic theorems. This unique feature of the book calls for a closer look at contents and methods with an emphasis on subjects outside the mainstream. Exercises, which range from routine to demanding, are dispersed throughout the text and some include an outline of the solution. Applications from mechanics to mathematical biology are included and solutions of selected exercises are found at the end of the book. It is suitable for mathematics, physics, and computer science graduate students to be used as collateral reading and as a reference source for mathematicians. Readers should have a sound knowledge of infinitesimal calculus and be familiar with basic notions from linear algebra; functional analysis is developed in the text when needed.

Elementary Differential Equations, Second Edition is written with the knowledge that there has been a dramatic change in the past century in how solutions to differential equations are calculated. However, the way the topic has been taught in introductory courses has barely changed to reflect these advances, which leaves students at a disadvantage. This second edition has been created to address these changes and help instructors facilitate new teaching methods and the latest tools, which includes computers. The text is designed to help instructors who want to use computers in their classrooms. It accomplishes this by emphasizing and integrating computers in teaching elementary or ordinary differential equations. Many examples and exercises included in the text require the use of computer software to solve problems. It should be noted that since instructors use their own preferred software, this book has been written to be independent of any specific software package. Features: Focuses on numerical methods and computing to generate solutions Features extensive coverage of nonlinear differential equations and nonlinear systems Includes software programs to solve problems in the text which are located on the author's website Contains a wider variety of non-mathematical models than any competing textbook This second edition is a valuable, up-to-date tool for instructors teaching courses about differential equations. It serves as an excellent introductory textbook for undergraduate students majoring in applied mathematics, computer science, various engineering disciplines and other sciences. They also will find that the textbook will aide them greatly in their professional careers because of its instructions on how to use computers to solve equations.

What is sustainability? Much has been said about the terms ‘sustainability’ and ‘sustainable development’ over the last few decades, but they have become buried under academic jargon. This book is one of the first that aims to demystify sustainability so that the layperson can understand the key issues, questions and values involved. Accessible and engaging, the book examines the ‘old’ sustainability of the past and looks to the future, considering how economic, ecological and social sustainability should be defined if we are to solve the entwined environmental, economic and social crises. It considers if meaningful sustainability is the same as a ‘sustainable development’ based on endless growth, examining the difficult but central issues of overpopulation and overconsumption that drive unsustainability. The book also explores the central role played by society’s worldview and ethics, along with humanity’s most dangerous characteristic – denial. Finally, it looks to the future, discussing the ‘appropriate’ technology needed for sustainability, and suggesting nine key solutions. This book provides a much-needed comprehensive discussion of what sustainability means for students, policy makers and all those interested in a sustainable future.
